Which of the following equations describes a straight line with a y-intercept of -2 and a slope of -5?
A)y = -5 - 2x
B)y = -2
C)y = -2 - 5x
D)y = -5x
E)x = -2 - 5y

Question

Quizplus · Accepted Answer

The standard form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept. Therefore, the equation with a y-intercept of -2 and a slope of -5 can be written as y = -5x - 2. Option A also has a slope of -5 but the y-intercept is incorrect. Option B has the correct y-intercept but does not include the slope. Option D has the correct slope but does not include the y-intercept. Option E has the variables x and y switched and does not include a y-intercept.
