Standard Form
4x + y = -9
y = -4x - 9
The repair shop charges $79 for a new muffler plus
$40 per hour of labor.
Write an eqwuation in slope-intercept form (y=mx+b).
y = 40x + 79
5x + 2y = 14
y = -5/2x + 7
The Durango Movie Theater charges a fee of $100 to rent the theater, plus $5 per student.
Write an equation to solve this and figure out how much would it cost to bring 34 students?
y = 5(34) = 100
$270
x - y = 5
y = x - 5
The Cortez carnival charges $7 to enter, and an additional $3 per ride.
Write this as an equation in slope-intercept form, and find the total cost if you rode 8 rides.
y = 3x + 7
$31
x - 5y = 10
y = 1/5x - 2
The repair shop charges $79 for a new muffler plus
$40 per hour of labor.
If Karen's bill was $159, find the number of labor hours.
x = 2 hours of labor
8x - 6y = 0
y = 4/3x
Gravity lab charges $150 to bring a school group, and an additional $12 per student. How many students went if the total cost was $306?
