<span>5 and 764 over 999
Converting a repeating decimal into a rational fraction is easy to do. So let's do it and see what we come up with to compare against the available options.
5.764764764 ...
It's obviously 5 + some fraction 0.764764764 ... so
X = 0.764764764 ...
1000 X = 764.764764764 ...
- X 0.764764764 ...
999 X = 764
X = 764/999
So the answer is 5 and 764/999
Looking over the available options, only the response
"5 and 764 over 999" matches.</span>
Answer:
Im taking this right now so Im not 100% sure
Step-by-step explanation:
y-intercept: 2 because the slope is passing through 2.
slope: take points (-1,2) and (-1,3)
m=Y2-Y1/X2-X1
m=3-2/-1-1
m=-1/2 or 1/-2(there is no difference)
so the slope is -1/2
b=2
in slope intercept, its going to be:y=-1/2x+2
btw, i noticed that the point isn't -1 it's 0.75 i think. Substitute the -1 for -0.75(-3/4) and finish the math. Sorry.

10s^2-15s+20 because 5(2s^2)=10s^2, 5(-3s)=-15s, and 5(4)=20.
