100
The distance from zero to x on a number line.
What is absolute value?
100
Write in slope - intercept form. slope = -2/3 ; y intercept = 2
What is y = -2/3x + 2?
100
State whether this is a direct variation. If so, name the constant. 3y = 4x + 1
What is no because y = 4/3x + 1/3?
100
Solve by substitution. x - y = -3 5x + 3y = 1

100
Find the product. 120 x 32
What is 3840?
200
Name this form. y – y1 = m(x – x1)
What is point - slope form?
200
Write in slope - intercept form. 2x + y = 8
What is y = -2x + 8?
200
State whether this is a direct variation. If so, name the constant. y + 3x = 0
What is yes because y = -3x. The constant is -3.
200
Solve by substitution. y = x + 3 y - 2x + 4
What is x = -1; y = 2?
200
