Question

if y=mx+b, find m and use the formula for the previous question to find m when the coordinates are (4,7) and b=12​

Answer 1

m = -5/4

Explanation:

In the slope-intercept form formula, y = mx + b, substitute 4 for x, 7 for y, and b for 12 to solve for m.

y = mx + b

7 = 4m + 12

-5 = 4m

m = -5/4
