Answer:
5x+5y=15
Step-by-step explanation:
Standard form is Ax + By = C, or By = C - Ax.
Dividing both sides by B, we get y = C/B - (A/B)x
Here the y intercept is C/B, and the slope is -A/B.
Answer:
D. 100°
Step-by-step explanation:
A straight line is 180°. Add 50° and 30° (which is 80°) and subtract the total from 180°.
50 + 30 = 80
180 - 80 = 100
Step-by-step explanation:
It's an irrational number.
