Question

Which table shows the relationship y = 50x?

Answer 1

Answer:

$\displaystyle y = \frac{4}{5}x$

B. x 1 3 4 5

y 50 150 200 250

Step-by-step explanation:

First, find the rate of change [slope]:

$\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{0 + 24}{0 + 30} = \frac{24}{30} = \frac{4}{5} \\ \\ y = \frac{4}{5}x$

We can write the equation from here, since both the x-intercept and y-intercept are at the origin.
