Slope, found using the points is -55/11 = -5
We use that for the equation y=mx+b where m=-5. Since we also know one of the points, we can plug that in and find b
-12=-5(4)+b
-12=-20+b
8=b
So the equation of the line is y=-5x+8
Angle w equals 130 degrees.
Explanation:
A line equals: 180 degrees total.
180-50=130
The in is -5 the out for 7 is -21 the out for -3 is 9the infor 15 is -5 the out for -10 is 30
