This is the question:

MrRissso [65]

Answer:

$y = \frac{10}{3}x$

B) 240 pages

Step-by-step explanation:

From the table, he can read 20 pages in 6 minutes and 15 paged in 50 minutes.

The unit rate can be found using

$m = \frac{change \: in \: y}{change \: in \: x}$

$m = \frac{50 - 20}{15 - 6}$

$m = \frac{30}{9} = \frac{10}{3}$

Using the point (6,20) and the unit rate we can find the equation using

$y-y_1=m(x-x_1)$

$y - 20 = \frac{10}{3}(x - 6)$

$y=\frac{10}{3}x - 20 + 20$

$y = \frac{10}{3}x$

B) When x=72 minutes we substitute

$y = \frac{10}{3} \times 72$

$y = 10 \times 24 = 240$
