Hi there!
To convert an equation from standard form to slope-intercept form, you need to pull the x over to the other side by making it 0 (by either subtracting or adding that number on both sides):
4x + 2y = 10----> 2y = -4x + 10
Now, we simply divide both sides by the coefficient on y and there you have it!
y = -2x + 5
Based on the given variation, y does not vary directly with x and the constant of variation are 8, 3.2 and 1.25 respectively.
<h3>Variation</h3>
y = k × x
where,
k = constant of proportionality
y = -40
x = -5
y = k × x
-40 = k × -5
-40 = -5k
k = -40/-5
k = 8
when,
y = 8 and x = 2.5
y = k × x
8 = k × 2.5
8 = 2.5k
k = 8/2.5
k = 3.2
when,
y = 5 and x = 4
y = k × x
5 = k × 4
5 = 4k
k = 5/4
k = 1.25

I'm really not sure about the top and bottom answer but I know i can help you with 10. Anyways, to figure this out you just need to know how many minutes are in 5/6 of an hour than multiply that many minutes by 5, I think i'll let you figure this out. :)
(Answer is 250 minutes if you don't want to figure it out)
C is the answer because the X factors can’t repeat
48－4=44,in the left
6×7=42,in the right
44＞42,so ＞ is the answer
