Answer:

<em>a = - 10</em>

Step-by-step explanation:

<em>3a – 8 = 5a + 12</em>

<em>3a – 8 + 8 = 5a + 12 + 8</em>

<em>3a = 5a + 20</em>

<em>3a - 5a = 5a + 20 - 5a</em>

<em>- 2a = 20</em>

<em />\dfrac{-2a}{-2}=\dfrac{20}{-2}<em />

<em>a = - 10</em>

Write an equation in slope-intercept form that goes through the points (-3, -4) and (3,4).
Marat540 [252]

Answer:

Y = 4/3x + 0

Step-by-step explanation:

(-3,-4) and (3,4) can be plugged in to rise over run.

y 4 -(-4) = 8

x 3 - (-3) = 6

8/6 = 4/3

Plug into slope intercept form

4 = 4/3(3) + b

4 = 12/3 +b

4 = 4 +b

Subtract from both sides

0 = b

Y = 4/3x + 0
