Let l be a line in the x-y plane. If l is a vertical line, its equation is x real number a. Suppose l is not a vertical line and its slope is m. Then the equation of l is y = mx + b, where b is the y-intercept. If l passes through the point (xo, Yo), the equation of l can be written as y – Yo points in the x-y plane and x1 # x2, the slope of the line passing through these points is 2 - 41)/(x2 – x1). Write a program that prompts the user for two points in the x-y plane. The program determines whether the line is vertical, horizontal, increasing, or decreasing, and outputs the equation of the line. Your program should at least have the following functions: = a for some m(x – xo). If (x1, Y1) and (x2, Y2) are two т — • a function to prompt the user to enter a point. • a function to determine whether the line is vertical, horizontal, increasing or de- creasing. • a function to display the equation of the line.

Let l be a line in the x-yplane. If l is a vertical line, its equation is x = a for some real number a. Suppose l is not a vertical line and its slope is m. Then the equation of l is y = mx + b, where b is the y-intercept. If l passes through the point (x₀, y₀), the equation of l can be written as y - y₀ = m(x - x₀). If (x₁, y₁) and (x₂, y₂) are two points in the x-y plane and x₁ ≠ x₂, the slope of line passing through these points is m = (y₂ - y₁)/(x₂ - x₁). Instructions Write a program that prompts the user for two points in the x-y plane. Input should be entered in the following order: Input x₁ Input y₁ Input x₂

Let L be a line in the xy plane. If L is a vertical line, its equation is x=afor some real number a. Suppose L is not a vertical line and its slope is m. Then the equation of L is y=mx + b, where b is the y-intercept. If L passes through the point (x0,y0), the equation of L can be written as y –y0=m(x –x0). If (x1,y1)and (x2,y2)are two points in the xy plane and x1≠x2, the slope of the line passing through these points is m = (y2-y1)/ (x2-x1). Write a program that prompts the user to enter two points in the xy plane. The program outputs the equation of theline and uses ifstatements to determine and output whether the line is vertical, horizontal, increasing, or decreasing. If L is a nonvertical line, output its equation in the form y=mx + b.

This is a Computer Graphics Question on Phong's Lighting Model. Question: A light source with intensity 50 and radius of influence 100 is located at (4,2,93) from which you are called to calculate the illumination of a point on the yz plane. For no shiny surface and negligible ambient light, find the point on the surface with the highest illumination and light intensity at that point. Given the diffuse coefficient is 0.7.

Q1/ The ideal gas equation of state is given by: PV = nRT Where: P is the pressure (atm), V is the volume (L), T is the temperature (K), R=0.08206 (L atm)/(mol K) is the gas constant, and n is the number of moles. Real gases, especially at high pressures, deviate from this behavior. Their responses can be modeled with the van der Waals equation: P-- nRT n² a + = 0 V-nb V2 Where a and b are material constants. For CO₂ a 3.5924 L'atm/mol², and b=0.04267 L/mol. Calculate P from both equations for CO₂ gas with 40 values of V between 0.01 and 1.5 and display the results in: 1- Three-column table where the values of Vand both P are displayed in the first, second, and third columns, respectively. 2-Plot V versus both P in two different plots in the same figure with a solid line, black color, with circle marker. Add a title, labels, and the grid to the plot. Make all texts bold with font size of 13. Take T-298K and n-3 moles.

Imagine that you are facing an infinitely long wall, and you need to reach the only door in the wall. You may walk along the wall to your left or to your right, and at any time you may turn and walk in the opposite direction. You are in fog, so you only know where the door is when you are right in front of it. Assume that the door is an (unknown, but finite) integer number of steps away. As a function of the (possibly unknown) distance to the door, give an algorithm and cost for the minimum number of steps (in the worst case) that you must walk to reach the door in the following situations. For each situation, you should describe the (best) procedure that you could follow and analyze its worst-case cost: (a) You know the door is to your left. (b) You don’t know where the door is, but you know that it is exactly n steps away. (c) You don’t know where the door is, but you know that it is at most n steps away
