Question

What is the equation of the line with m = 2.5 and b = 7? A. y = −2.5x − 7 B. y = 2.5x −7 C. y = −2.5x + 7 D. y = 2.5x + 7

Answer 1

y=2.5x+7

Explanation:

You are basically being asked to use slope-intercept form for linear equations. It says y=mx+b where m is the slope and b is the y-intercept.

Plug in 2.5 for m and 7 for b giving you y=2.5x+7.

Answer 2

The equation is: y = mx + b

y = 2.5x + 7

so it's option D.
