Find the equation of the line specified. the slope is -4, and it passes through ( 5, 8). a. y = -4x + 8 c. y = -4x - 12 b. y = -4x + 28 d. y = -8x + 28

ANSWER

EXPLANATION

The given line passes through (5,8).

The slope of this line is m=-4.

We use the point-slope formula;

We substitute the point and slope into the formula to get;

We expand to get:

This simplifies to:

After graphing, you can see that B.) y = -4x + 28 clearly passes through (5,8)
