Answer:
y = 4
Step-by-step explanation:
8(y + 4) - 2(y - 1) = 70 - 3y ← distribute parenthesis and simplify left side
8y + 32 - 2y + 2 = 70 - 3y
6y + 34 = 70 - 3y ( add 3y to both sides )
9y + 34 = 70 ( subtract 34 from both sides )
9y = 36 ( divide both sides by 9 )
y = 4

Answer:
2 and a half
Step-by-step explanation:
If you know the slope of a linear relationship as well as one of the points, you can determine if the relationship is proportional if the value of y is equal to the value of the slope times the x value.
<h3>When is a relationship proportional?</h3>
The linear relationship of x and y is said to be proportional if:
y = slope × x
This means that the value of y is directly related to the value of x such that when x is increased by a certain value, you get y.
If this condition is not satisfied then the relationship is not proportional.
The linear relationship above is therefore proportional if the value of y in the point is the same as x when multiplied by the slope.
