Question

How do I solve this problem?

Answer 1

You need to find x and y intercept
y = 1.25x - 2.5

x intercept y = 0 x =2.5/1.25 = 2
y intercept x = 0 y = -2.5

so your coordinates (0,-2.5)(2,0)

answer is A. (first graph)

Answer 2

You use a scientific or graphing calculator to plug in the equations then plot each point and connection the dots.
