Question

Write the equation in slope-intercept form. y=7(x+2)+3x

A. y=10x+14
B. y=−10x+14
C. y=9x+15
D. y=−9x+15

Answer 1

Answer: The answer is A (y=10x+14)

Answer 2

Answer: y = 10x+14 (choice A)

===================================

Work Shown:

y = 7(x+2)+3x

y = 7x+7*2+3x ..... distribute

y = 7x+14+3x

y = (7x+3x)+14

y = 10x+14

This is in y = mx+b form with m = 10 as the slope and b = 14 as the y intercept.
