Question

Complete the equation of the line through (-10, 7) and (5,9).Use exact numbers.Y=? Slope intercept from two points

Answer 1

`\begin{gathered} x_1=-10,y_1=-7,x_2=-5,y_2=-9 \\ y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1) \\ y+7=(-9+7)/(-5+10)(x+10) \\ y+7=-(2)/(5)(x+10) \\ 5y+35=-2x-20 \\ 5y=-2x-55 \\ y=-(2)/(5)x-11 \end{gathered}`
