Question

Can someone help me with number 10 please :(

Answer 1

Idk if your teacher will mind if the y-axis and the x-axis were different (x goes by 1's, y goes by 45) I also forgot to put a line....

To find the slope, use the slope formula and plug in 2 points. I will use (3, 135) and (5,225):

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$m=\frac{225-135}{5-3}$

$m=\frac{90}{2}$

m = 45

The slope is 45. This means that every minute, 45 words are something(typed/written/read - idk)
