A.5
B.-3
C.-5
D.3

Answers

Answer: C. (2, -5 )

Step-by-step explanation:

These are the coordinates of the points on the line

We can see (-3, 5) and (0, -1) on the line.

To find the y-coordinate of a point when the x-coordinate is 2, all you have to do is look for the x-intercept of 2 and look for the y-intercept.

When you look at the bottom of the graph, you can see that the x-coordinate 2 and the y-coordinate -5 intersect to form a point.

Hope that helped!
