400

A line passes through the points (-2, 6) and (3, 18). Find the slope/rate of change.

12/5

500

Convert to slope-intercept form:

y + 2 = 2/3(x - 9)

y = 2/3x - 8

System Showdown

100

Solve the system:

y = 3x

2x + y = 10

x = 2

y = 6

200

Solve the system:

4x + 2y = 14

2x - 2y = 4

x = 3

y = 1

300

Solve the system:

3x + 2y = 16

7x + y = 19

x = 2

y = 5

400

Solve the system:

5x + 3y = 2

4x + 7y = -26

x = 4

y = -6

Work Out Your Quads!

100

State the y-intercept of f(x) = 2x² + 5x - 7

(0, -7)

200

State the x-intercepts of f(x) = (x + 4)(2x - 6)

(-4, 0) and (3, 0)

300

Rewrite in factored form: x² + 8x + 12

(x + 6)(x + 2)

400

Solve for x: 2x² + 5x - 12 = 0

x = -4 & x = 3/2

500

Solve for x: 6x² - 4x - 100 = 20x + 92

x = 8 & x = -4
