Question

What is the equation of the line that has a slope of 4 and passes through the point (3, -10?)A.y=4x + 22B. y=4x - 43C. y=4x - 22D. y= 4x + 43

Answer 1

We have the information of one point and a the slope, so we can write the equation in the point-slope form:

$\begin{gathered} y-y_1=m(x-x_1) \\ y-(-10)=4(x-3) \\ y+10=4x-12 \\ y=4x-12-10 \\ y=4x-22 \end{gathered}$

The answer is C. y=4x - 22
