is equivalent to <span>

That is in the form </span><span>

which is point slope form
In this case,
m = 1/2 is the slope
(x1,y1) = (7,-8) is the point the line goes through</span>
are u looking for the slope?
The answer is to this question is c (5,-7)
The first option 12a - 20
(x+7)(x+3) so therefore you set each equation = 0...
x + 7 = 0
x + 3= 0
and solve
x = -3
x = -7
