Question

What is the slope of the equation below?

2y = 10x – 8
A.2
B.-8
C.10
D.5

Answer 1

=5(d)

Explanation:

in the equation y=mx+c:m is the gradient

2y=10x-8

divide by 2y on both sides to make y on the other side

y=5x-4

m=slope=gradient

Answer 2

D) 5

Explanation:

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Divide 2 from all terms within the equation:

(2y)/2 = (10x - 8)/2

y = (10x)/2 - (8)/2

y = 5x - 4

Note the slope-intercept form:

y = mx + b

y = y

x = x

m = slope

b = y-intercept.

In this case, 5 is in place of m, or your slope.

D) 5 is your answer.
