Answer:
y-2 = -2(x+1)
Step-by-step explanation:
Find the slope(m) first using the two points (3, -6) and (-1, 2).
Slope: -2
Next, plug in x₁ and y₁. I plugged in (-1, 2)
m^2 -11m -60 = 0
m^2 -11m =60
(m^2 -11m + 121/4) = 361/4
(m - 11/2)^2 = 361/4
m - 11/2 = + or - 19/2
m = 11/2 + 19/2, 11/2 - 19/2
m = 15, -4
---------------------------------------------------
m^2 -11m -60
(11 +- Square root (121 +240))/2
11/2 +- 19/2
m= 15, -4
----------------------------------------------------
m^2 -11m -60
(m - 15) (m + 4)
m = 15, -4
