Graph the equation
Answer to Problem 46PPS
Graph by using the x and y intercepts. They are x = − 10.5 and y = − 7
Explanation of Solution
Given:
The equation:
Concept Used:
The x -intercepts are where the graph crosses the x -axis, and the y -intercepts are where the graph crosses the y -axis.
Then, algebraically,
- an x -intercept is a point on the graph where y is zero, and
- a y -intercept is a point on the graph where x is zero.
More specifically,
- an x -intercept is a point in the equation where the y -value is zero, and
- a y -intercept is a point in the equation where the x -value is zero.
Calculation: The equation:
We can graph the equation by using x and y − intercept method. First we find the x and y intercept from the equation and then plot the points on the grid and join then to complete the graph.
Find the x − intercept, plug in y = 0 in the equation.
Find the y − intercept, plug in x = 0 in the equation
Graph the line
Thus, x and y intercepts are x = − 10.5 and y = − 7
