2
Find the slope of this line.
3
Find the slope given this equation: y = 4x - 4
4
Find the slope using this table. XY -4-17 -2-11 0-5 21 47
5
Find the slope of a line given these points on the line: ( -4,8) (3, -2)
6
Give the slope and y-intercept of the line that has passes through these points (3,0) (6,2).
7
Give a 2 nd point that would fall on the line that passes through (5,4) and has a slope of ½.
8
Write the equation of this line:
9
Identify which if any pairs of equations are parallel or perpendicular: A) y = 3x + 4 E) y = 3x + 2 B) y = 4x – 3 F) y = 4x C) y= -1/3x G) y= 1/3x +8 D) y= -0.25x +6
10
Write 2 equations that are parallel to one another & Write 2 equations that are perpendicular to one another.
12
Tell if each is an example of direct variation or inverse variation: A) Height of a person vs. wingspan B) Number of people who buy a lottery ticket and the odds that you will win C) Number of people at a picnic and amount of watermelon that you get
13
Tell if these are examples of direct of inverse variation: XY 819 921 1227 XY -35 -410 -515 XY 20-20 21-25 22-30
14
Identify each graph as having either direct or inverse variation:
15
Identify each equation as either inverse (I) or direct(D) variation: A) y = -3x B) y = -10/x C) y = 10 D) x = 50000/y E) y = 3x 2
16
Give an example (not already used today) of direct variation & an example of inverse variation.
