-m = - 4, y-intercept (0, -7)
A) y = - 4x
B) y = - 4x - 7
C) y = - 7x - 4
D) 4x + y = - 7

Question

Quizplus · Accepted Answer

The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept. We are given that m = -4 and the y-intercept is (0,-7). 
Substituting these values into the slope-intercept form, we get: 
y = -4x - 7 We are given that the slope is -4 and the y-intercept is (0,-7). 
Using the slope-intercept form, we have:
y = mx + b 
y = -4x - 7 (Substitute m = -4 and b = -7) 
Therefore, option B is the correct answer.
