Linear Models- Algebra

Question

If  is a linear function, , and , find an equation for  in slope-intercept form.

Answer 1

(-4,-5) and (3,0) are two points on the line. It has slope (5-0)/(-4-3) = 5/-7 = -5/7=m

y=mx+b where m=slope and b= y intercept

y=(-5/7)x + b plug in either point to calculate b

0=(-5/7)(3) + b

b = 15/7

y=(-5/7)x + 15/7
