Question

Complete the equation of the line through (4,-8)and (8,5) use exact numbers

Answer 1

`\begin{gathered} y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1) \\ y-(-8)=(5-(-8))/(8-4)(x-4) \\ y+8=(13)/(4)(x-4) \\ 4(y+8)=(13)/(4)(x-4)*4 \\ 4(y+8)=13(x-4) \\ 4y+32=13x-52 \\ 13x-4y=84 \end{gathered}`

thats the equation
