pentagon [3]

Answer:

y = -3x + 8

Step-by-step explanation:

You have to find the slope first using the formula \frac{y_{2}-y_{1} }{x_{2}-x_{1}}

Insert any two points in the equation (1,5) and (2,2) and you get -3.

Then, you do any x value times the slope (1*-3 = -3) and add so that it equals the corresponding y value (8).

This makes it y = -3x + 8.

Simplify<br><br> a+a+a=<br> 4b-b<br> 3x2+x2
Reika [66]
<h2>Good morning,</h2>

<em><u>__________________</u></em>

<em><u>Answer</u></em>:

a+a+a = 3a.

4b-b = 3b.

3x²+x² = 4x².

<u><em>explanation</em></u>

a+a+a = 3a.

4b-b = b(4 - 1) = b × 3 = 3b.

3x²+x² = x²(3 + 1) = x² × 4 = 4x².
