It is saying that 80/100 which is .80, so 50*80%= 40

answer: 10/4 reduced is 2.5/1 or 2.5.
work: what we are doing is trying to divide ten into groups of four. how many times does 10 fit into four? well, look at the multiples of four, 4, 8, 12... we can see that 8 fits into ten, but 12 doesn't. that means two whole fours can fit into ten (since 4 x 2 = 8) so we still have a 2 left over from the ten. since 2 is one half of four, we can fit in another .5. so, ten can be fit into 2.5 groups. hope this helps, have a great day!
The line y=7 is a horizontal line with a slope of 0.
Slope intercept form of
y=mx+b
would be
y-y1=m(x-x1)
m=0 and point of (-1,-10)
y-(-10)=0
y=-10
