Answer:

The value of y is 9¼.

Step-by-step explanation:

Given that the slope of the set of points (10,y) and (3,4) is 3/4.

Using the slope formula:


\text{Slope},m=\frac{Change\text{ in y-axis}}{Change\text{ in x-axis}}

We have:


(3)/(4)=(4-y)/(3-10)

We then solve for y:


\begin{gathered} (3)/(4)=(4-y)/(-7) \\ \text{Cross multiply:} \\ 4(4-y)=-21 \\ 16-4y=-21 \\ -4y=-21-16 \\ -4y=-37 \\ y=(-37)/(-4) \\ y=9(1)/(4) \end{gathered}

The value of y is 9¼.
