Question

Complete the equation for the linear function whose graph contains the point (7, 8) and has a slope of −1.2.

Answer 1

Your answer is to the question 16,4
Form of the equation: y = mx + b
---
You are given that y = 8 when x = 7.
And you are given that m = -1.2
-----
Substitute for those letters and solve for "b"::
8 = -1.2*7 + b
8 = -8.4 + b
b = 8 + 8.4 = 16.4
