Answer:
y = -1/4x-6
Step-by-step explanation:
y=mx+b
Use slope equation m = (y1 - y2) / (x1 - x2)
b is the y intercept : -6
The answer is 13/20. So 3/5 is equal to 6/10 so you're looking for the fraction that's half of 7/10 and 6/10 which is 6.5/10 but you can't use decimals in a fraction so you multiply both sides by 10 which would equal 65/100 and simply, and that would be 13/20.
Supplementary angles
x+20+5x+10=180
6x+30=180
6x=150
x=25
5x-7x=-8
-2x=8
x=-4
this is how to solve it
