• 4

• 1

• ⅓

• ¼

What are the coordinates of point B ?

• (17, 0)

• (0, 17)

• (1, 7)

• (10, 17)

What is the equation of a line with a slope of - ⅓ and y-intercept of 8 ?

• y = -0.3x + 8

• y = 8x - 0.3

• y = 0.3x - 8

• y = 0.3x + 8

Joan gets a job planting trees for the summer. At the beginning of the season, she owes the company she works for $440.00 for food and lodging. She makes $1.25 for every 10 trees she plants. How many trees must Joan plant in order to break even?

• Joan breaks even after planting 3250 trees.

• Joan breaks even after planting 5320 trees.

• Joan breaks even after planting 3020 trees.

• Joan breaks even after planting 3520 trees.

Slope of parallel lines are:

• Always 7

• Opposites

• Negative reciprocals

• The same

These lines are ______.

Slopes of perpendicular lines are ________.

Solve the system of equations below using the substitution method

Line 1: 6x + 18y = 69

Line 2: 10.75 + y = 8x

• x = 0.75, y = 3.25

• x = 1.25, y = 3.25

• x = 3.25, y = 1.75

• x = 1.75, y = 3.25

New York City is a popular field trip destination. This year and last, the senior class at Mac High planned trips there.

Last year, the senior class rented and filled 1 van and 6 buses with 324 students. This year, the senior class filled 9 vans and 3 buses with 264 students.

Every van had the same number of students in it, as did the buses.

i) How many students can a van carry?

ii) How many students can a bus carry?

• a van can carry 32 students, a bus can carry 12 students

• a van can carry 42 students, a bus can carry 52 students

• a van can carry 12 students, a bus can carry 52 students

• a van can carry 12 students, a bus can carry 52 students

Are the following equations parallel, perpendicular or something else? 

Line 1: -4x + 2y + 16 = 0

Line 2: 6y = -3x + 6

• Parallel

• Perpendicular

• Neither Parallel, nor Perpendicular

• The same
