anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

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

Satellite beat me to it :)

anonymous · Answer

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
