Slope Formula:
y2-y1/x2-x1
First, let's solve what we already know.
∆-3/4-(-2) = -5/3
∆-3/6 = -5/3
Now, we know that ∆ has to be a number that when subtract equals a number that can be divided by 2 to get -5.
(x − 3) * (3) = (−5 * 6)
3x − 9 = −30
3x − 9 + 9 = −30 + 9
3x = -21
3x/3 = -21/3
x = -7
Hence, ∆ equals -7.
