Question

X+1/2y=4
Solve the equation for Y

Answer 1

X+1/2y = 4
(X+1)*2y=4*2y
2xy+2y=8y
2*y=8y-2y
2xy=6y
2x=6
X=3

3+1/2y=4
4/2y
Y=16

Answer 2

Answer:8/1

Explanation:

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 8.000 and for x=2.000, the value of y is 4.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 4.000 - 8.000 = -4.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
