Question

Find the equation of the line specified. The line passes through the points ( 7, -7) and ( 6, -5)

Answer 1

Simple...

you have: (7,-7) and (6,-5)

Using $\frac{ y_{1}- y_{2} }{ x_{1}- x_{2} }$ to find slope--->>>

$\frac{-7--5}{7-6} = \frac{-2}{1}$

=-2

m=-2

Using y=mx+b to find the equation of the line-->>(Use any of the coordinates)

(7,-7)

-7=-2(7)+b

-7=-14+b

-7=-14+b
+14  +14

7=b

y=-2x+7

Thus, your answer.
