Step-by-step explanation:
Since the three given points represent a straight line, we can construct a table to go to the point where x=0, the y-value will be the y-intercept.
-36 -117
-27 -98
-18 -79
We note that for every increase of 9 in x, there is an increase of 19 in y.
so continuing:
-9 -60
0 -41 (y-intercept)
Answer: y-intercept is (0,-41)
Answer:
