Answer:

a = -3/2

Step-by-step explanation:

3(6a+12)=9

Divide each side by 3

3/3(6a+12)=9/3

6a+12 = 3

Subtract 12 from each side

6a+12-12 = 3-12

6a = -9

Divide by 6

6a/6 = -9/6

a = -3/2

Which is the equation of the given line in slope-intercept form? (-1, 2) and (1, -4)

Natalka [10]

1. Find the slope using the slope formula.
$\frac{2 - ( - 4)}{ - 1 - 1} = \frac{2 + 4}{ - 2} = - \frac{6}{2} = - \frac{3}{1} = - 3$
2. Plug that slope and either point into an equation in slope-intercept form and solve for b.
$2 = - 3( - 1) + b \\ 2 = 3 + b \\ - 1 = b$
3. Now write your answer as a slope-intercept form equation
$y = - 3x - 1$
