y=2x+23/5
Step-by-step explanation:
Answer:
A. 45 and 135
Step-by-step explanation:
Recall: two angles on a straight line forms a linear pair. The pair sum up to 180°.
Thus:
✔️c° + 3c° = 180°
4c = 180
Divide both sides by 4
4c/4 = 180/4
c = 45°
✔️3c = 3(45) (substitution)
= 135°
Let's use the point-slope equation y - k = m(x - h).
substituting (2, -1/2) and slope = 3, we then get:
y + 1/2 = 3(x-2).
