The first step is to determine the slope.
m = ( y2-y1)/(x2-x1)
m = ( -4 - -2)/( 3 - 5)
= (-4+2)/( 3-5)
= -2 / -2
= 1
Point slope form of the equation
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y - -2 = 1(x -5)
y+2 = x-5
or
y - -4 = 1(x-3)
y+4 = x-3
To change this to slope intercept form y= mx+b where m is the slope and b is the y intecept
Subtract 4 from each side
y+4-4 = x-3-4
y = x-7
We can also do it with the first equation
y+2-2 = x-5-2
y = x-7
