5
How many quadrants make up the Coordinate Plane?
4
What happens to line when the slope gets bigger? (coefficient)
It gets steeper
Give an example of a real-world problem that would only use the first quadrant.
Example should have a positive independent and dependent.
If a person saves $40 a week for 3 weeks and starts with $50, what is the initial value?
$50
Write an equation for a linear function going through the origin with a slope of -2.
y=-2x
If reading a graph from left to right, the linear equation is in a downward position, what type of slope is it?
negative
What do you call the slope of a completely vertical line?
Undefined or no slope

9
Write an equation for a horizontal line with a y-intercept of 3.
y=3
Describe the graph of y = 2/3x-5
It starts at -5 and goes up to the right at a rate of over 3 and up 2.
What is the slope of the line passing through (5, 7) & (-1,0)?
7/6
What is the equation of a line with an initial value of 0 and a slope of 3?
y=3x
What is the equation of the line with a y-intercept of 8 and a slope of 1⁄2?
y=1⁄2x+8
Put these lines in order from least steep to most steep:
y = 1/3 x + 4, y = 5x -7, y = -2x, y = 8
y = 8, y = 1/3 x + 4 , y = -2x, y = 5x - 7

(0,18) (3,4) (9,0) (12, 2)
(9,0) (12, 2)
What is the y-intercept of the line passing through (3, 7) and (4, 9)?

Negaive
What would the equation of the line be that passes through (4, 7) and (2, 8)?
y = -1/2x + 9
