M=-4/5,(-7, - 2) Find the equation of the line that has the given slope
ikadub [295]

Answer: y=-\frac{4}{5}x-\frac{38}{5}

Step-by-step explanation:

To find the equation, you plug in the slope and given point. Then, you can solve and find the y-intercept.

-2=-\frac{4}{5}(-7)+b          [multiply]

-2=\frac{28}{5}+b                  [subtract both sides by \frac{28}{5}]

b=-\frac{38}{5}

Now that we have the y-intercept, the equation is y=-\frac{4}{5}x-\frac{38}{5}.
