Question

plot the point on this function with a y-value of 4.
what is the x-value of this point?

Explanation:

Step1: Identify the linear function

First, find the equation of the line. The line passes through $(0,0)$ and $(10,8)$, so its slope is $\frac{8-0}{10-0} = \frac{4}{5}$. The equation is $y = \frac{4}{5}x$.

Step2: Solve for $x$ when $y=4$

Substitute $y=4$ into the equation:
$$4 = \frac{4}{5}x$$
Multiply both sides by $\frac{5}{4}$:
$$x = 4 \times \frac{5}{4}$$
