$(\stackrel{x_1}{-7}~,~\stackrel{y_1}{-2})\qquad (\stackrel{x_2}{-2}~,~\stackrel{y_2}{-22}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-22}-\stackrel{y1}{(-2)}}}{\underset{run} {\underset{x_2}{-2}-\underset{x_1}{(-7)}}}\implies \cfrac{-22+2}{-2+7}\implies \cfrac{-20}{5}\implies -4$

$The\ slope-intercept\ form:\\\\y=mx+b\\\\m-the\ slope;\ b-the\ y-intercept\ form$

$the\ slope:\\\\m=\frac{5\ miles}{1.4\ hours}=\frac{50}{14}\ mph=\frac{25}{7}\ mph\\\\so,\ therefore:\\\\\boxed{y=\frac{25}{7}x}$

Can you hlep me on 1,2,3 please and thank you.

hichkok12 [17]

1. - We need to add fractions

4 6/8 + 3 2/3 = 8 1/2

2. Adding fractions.

8 1/2 + 4 2/4 = 13

3. Once again, adding fractions.

2 4/6 + 5 1/2 = 8 1/6

Those are the answers to 1, 2 and 3!

Please know that these were from my mind, so they may be wrong.
Although, I did my best, and I think they are all right.

Glad I could help, and good luck!

That is 12/5 miles or 2 2/5 miles

In decimal, that's 2.4 miles
