Step-by-step explanation:
supplementary angles.
Answer:
(0, -9) (1, -5)
Step-by-step explanation:
We know from the equation y = 4x -9, that the slope of the line is 4, and the point that the line crosses the y-intercept is at -9. So, your first point would be at (0, -9) and if you go one value over on the x-coordinate, that means the y-coordinate will go 4 up. So your final point will be (1, -5). The point could also be (2, -1), (3, 3), (4, 7), (5, 11), etc.
I Hope That This Helps! :)
The answer is C.
(0, 3)
y = x + 3
3 = 0 + 3
3 = 3
(1, 4)
y = x + 3
4 = 1 + 3
4 = 4
(2, 5)
y = x + 3
5 = 2 + 3
5 = 5

Step-by-step explanation:
the ratio of the opposite interior angles = 8 : 9 = 8x : 9x
The exterior angle of a triangle = sum of the opposite interior angles, hence
8x + 9x = 119
17x = 119 ( divide both sides by 17 )
x = 7
8 parts = 8x = 8 × 7 = 56
9 parts = 9x = 9 × 7 = 63
The sum of the 3 angles in a triangle = 180°
subtract the sum of the 2 angles from 180 for third angle in triangle
180° - (56 + 63)° = 180° - 119° = 61°
The 3 angles of the triangle are 56°, 61°, 63°
