Hi,

linear function f that has the indicated values

(-3,1) and (-8,7) points of the line

y = mx + b  the general slope intercept form of a linear equation.

m = 7-1 / -8 -(-3)

m = 6/-5

y = (-6/5)x + b using Pt (-3,1) to solve for b

1 = (-6/5)*-3 + b

5/5 - 18/5 = b

-13/5 = b

y = (-6/5)x - 13/5
