You have $135 in a savings account and save $12 per week. Your friend has $95 in a savings account and saves $20 per week. Which equation represents how many weeks it will take for you and your friend to have the same balance?

• 95 + 12x = 135 + 20x

• 135 - 12x = 95 - 20x

• 135 + 12x = 95 + 20x

• 95 - 12x = 135 - 20x

Write the equation in slope-intercept form using the given information: passes through (-2, 1) and (2, -5).

• $y=-\frac{3}{2}x-2$

• $y-1=-\frac{2}{3}\left(x+2\right)$

• $y=-\frac{2}{3}x-2$

• $y+5=-\frac{3}{2}\left(x-2\right)$

Solve the equation: 5(-5k - 5) = 100

• k = 5

• k = 3

• k = -3

• k = -5
