The two angles are adjacent on a straight line so they are supplementary. Thus 8x+5+13x-14=180
21x-9=180
21x=189
x=9
You are correct about the y-intercept. In case you are unsure about the slope, you can check using y1 - y2 / x1 - x2:
(0, -1) and (1, 2)
-1 - 2 / 0 - 1
-3 / -1
3
The slope is 3; you chose the correct answer, great job.
Answer:
P(-3 , -2)
Step-by-step explanation:
Answer:
C. Points L,J and K are collinear.
Step-by-step explanation:
Collinear points are points that lie on the same line. So in the picture only the points L,J and K are collinear.
