The answer is -5. -5 times 4 is -20, plus 9 is -11. -5 times 2 is -10, -1 is -11. -5 works.
Answer:
y=(1/4)x - 35/2
Step-by-step explanation:
y=mx+b
y=(x/4)+b plug in the slope (m)
-18=(-2/4)+b plug in x and y
b= -17 1/2= -35/2 solve for b
y=(1/4)x - 35/2 plug in m and b into the equation
1) first one....90-27=63°
2)180-128=52°>>>>that is B
3)first one is suppliment....so A
4)180-125=55°....I think D....but not in pic !!!
so...go for it !!!
