Answer 2

The slope first which would be done by using the formula y2-y1/x2-x1. or -2-2/5-3= -4/2 =-2

Answer 3

first find the slope. it is
\[m=\frac{y_2-y_1}{x_2-x_1}=\frac{-2-2}{5-3}=\frac{-4}{2}=-2\]

Answer 4

then apply the formula y-y1=m(x-x1)

Answer 5

then point slope formula
\[y-y_1=m(x-x_1)\]
\[y-2=-2(x-3)\] then solve for y
\[y-2=-2x+6\]
\[y=-2x+8\]

Answer 6

Satellite beat me to it :)

Answer 7

find slope
m = y2 - y1 / x2 - x1
m = -2 - 2/ 5 - 3
m = -4 / 2
m = -2

find b
y = mx + b

pick any co-ordinate
2 = -2 (3) + b
2 = -6 + b
2 + 6 = b
8 = b

your equation is
y = -2x + 8
