Page 2: Reviewing Linear Equations. Write the slope and y-intercept for each equation. y = -3x + 7 y = 6x – 5 y = x – 1/2 y = -3/4 x.

Write the slope and y-intercept for each equation.

y = -3x + 7

y = 6x – 5

y = x – 1/2

y = -3/4 x

Molly is opening an Irish dance studio. Her monthly rent on the studio space is $2000. Her average monthly utility bill is $430. And, she is spending $500 a month in advertising. If she charges $30 per class, how many clients will need to attend one class per week in order for Molly to break even? (Assume 4 weeks in a month.)
