Answer:
(0, 127.85714285714)
Step-by-step explanation:
To find the y-intercept of the line, you need to find the equation of the line first.
The format of an equation of a line is: y = mx + c where m is the slope and c is the y-intercept (which is what we want to find).
Slope =
=
=
Slope =
Thus, the slope of a line is -.
To find the y-intercept, we just have to put in the slope of the line in an ordered pair.
y = mx + c
-117 = -(-36) + c
-117 = 10 + c
c = -117 - 10
c = -127
Thus, the y-intercept of a line is (0, -127 ).
