Y = mx+c

m is the gradient and c is the y-intercept so

4 = m(4) + (-4)

4 = 4m - 4

4m = 8

m = 2

Ans: Y = 2x - 4

4 = 4m - 4
8 = 4m
2 = m

y = 2x - 4

How do you calculate percentage or find the per cent value

katovenus [111]

Answer:

Divide the number you want to find the percentage for by the total amount of items in that group. Then, multiply that value by 100.

Ex. There are 3 boys in a group of 4. What percentage of the group are boys?

$\frac{3}{4} =0.75$

$0.75*100=75$
