Answer:
180 degrees
Step-by-step explanation:
1: Assuming this line is linear, the first thing to do is find the slope.
The slope formula is
, so in this case, it is
, which comes to
. Then, use your slope and one of the points given to write the point-slope formula of the linear equation, and then written in standard form:
y=
x-
.
2. Use the same process as in question 1 to find:
y=-7x+11
Replace y with 4 and solve for x:
3x - 4(4) = 65
Simplify:
3x -16 = 65
Add 16 to both sides:
3x = 81
Divide both sides by 3:
x = 81/3
x = 27
