The slope of the line that goes through two points $(x_1, y_1)$ and $(x_2, y_2)$ is:

$\dfrac{y_1-y_2}{x_1-x_2}$

The two points we are given is (7,9) and (2,12). Substitute these values into the formula for the slope

$=\dfrac{12-9}{2-7}$

Simplify

$=\dfrac{3}{-5}$

Simplify again

$=-\dfrac{3}{5}$

This should be your answer. Let me know if you need any clarifications, thanks!

ivolga24 [154]

So, first what we should do is divide 2,046 by 62 to find the width of Lucas's banner.

2,046 / 62 = 33 The width of Lucas's banner is 33 cm.

Which means if the width of Emily's banner is 3x that:

3 x 33 = 99 Emily's banner is 99 cm in width.

So, your 2 answers are: 99 cm, division and multiplication. ;)
