Is the graph linear or non-linear (explain)?

Can you help me find the y-intercept, slope, equation (in slope-intercept form) and predicting the cost of an average college mathematics textbook in 2017?

A farm has an area of 50 Hectares (Ha). It is to be planted with tomatoes and potatoes. At most $8000 can be spent on planting. The planting cost for potatoes is $100/Ha and for tomatoes $200/Ha. Choose the graph that best shows the area of each crop that can be planted.

What is the equation represented in the line graphed below?

I am really struggling with 1-23

The percent of defects is the x-coordinate, while the percent of new machines is the y-coordinate. So, the table of values corresponds to the points   (25,32), (20,40), (15,50), (10,65), (5,70), (0,85).     Question Using the linear relationship graphed above, estimate the percent of new machines if there is 12% defects in the shoes at various production facilities.  Provide your answer below:   _____

Part one: Graph the circle (x-2)squared + (y-1)squared=25 Submit a screenshot of your graphed circle. Part two: For each point, determine if it is on the circle. If not, decide whether it is inside the circle or outside the circle 1. (4,0) 2. (-3,3) 3. (-2,-2)
