Linear Functions Practice Test

A line has slope $-3$ and passes through the point $(4,2)$. Which equation is the line written in point-slope form? Watch for sign errors when substituting the point into $y-y_1=m(x-x_1)$.

On a coordinate plane, a line passes through the points $(-2,3)$ and $(4,-9)$. Which equation represents the line in slope-intercept form $y=mx+b$? Several options have the correct slope but an incorrect intercept.
