(0,-1) and (3,-5)<br> Write in point slope form an equation of the line through each pair of points
natali 33 [55]

Answer:

y=\frac{-4}{3}x-1

Step-by-step explanation:

slope:

\frac{y2-y1}{x2-x1} \\=\frac{-5+1}{3}=\frac{-4}{3}

point slope formula:

y-y1=m(x-x1)

y-(-1)=\frac{-4}{3}(x-0)

y+1=\frac{-4}{3}x

y=\frac{-4}{3}x-1
