Answer:
D) 5
Step-by-step 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.

Answer:
y/x = 2.5
Step-by-step explanation:
y ∝ x
change ∝ to = by adding constant k or c
y = kx
Divide both sides by x
y/x = k, also k = y/x
Input the values
k = (7 1/2)/3. Change 7 1/2 to improper fraction to give 15/2
k = (15/2)/3
k =
÷ 3
Change the division sign to multiplication which will change 3 to its inverse(1/3)
k =
× 
k = 
Divide the numerator and denominator by 3 to get 5/2
k = 5/2
From y/x = k,input k into the eqn
y/x = 5/2
y/x = 2.5
Answer:
Subtract 8x8x from both sides of the equation.
y=32−8x
