Left to Right

<u>Algebra I</u>

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

<u>Step 1: Define</u>

Point (-1, 10)

Point (5, 2)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>

Substitute [SF]: $m=\frac{2-10}{5+1}$
Subtract/Add: $m=\frac{-8}{6}$
Simplify: $m=\frac{-4}{3}$

8t + 5 = 6t + 1<br><br> a<br> 2<br> b<br> -2<br> c<br> 7

Maksim231197 [3]

Answer:b -2

Step-by-step explanation:

8t + 5 = 6t + 1 subtract 1 from both sides

8t + 4 = 6t subtract 8t from both sides

4 = -2t divide -2 from both sides

-2 = t

Have a nice day :)

Answer:

It's the second answer

Step-by-step explanation:

A(7,5) B(-4,-1)

y-yA/yB-yA= x-xA/xB-xA

y-5/-1-5=x-7/-4-7

-11y+55=-6x+42

-11y=-6x-13

y=6/11×+13/11
