Angle M equals 45°
Angle N equals 15°
-3 + 7x = -12
First, simplify -3x + 7x to get 4x. / Your problem should look like: 4x = -12
Second, divide both sides by 4. / Your problem should look like: x =
Third, simplify

to 3. / Your problem should look like: x = -3
Answer:
x = -3

The equation would be y=3x-1
Point Slope Formula:
y - y1 = m(x - x1)
y - 5 = 3(x-2)
y - 5 = 3x - 6
+ 5 + 5
--------------------
y = 3x - 1
