Question 01/03
What does this equation y=mx represent?
A proportional relationship
A non-proportional realtionship
01
An equation with no slope
Question 02/03
01
What makes an equation proportional?
If the graph has a y-intercept
If the line is vertical
Has no Y-Intercept
Lesson 01
Question 03/03
What does b represent in the equation y= mx+b?
Y-Intercept
Slope
A point on the graph that line goes through

Question 01/03
What does the Slope represent in a graph?
The starting point of the line
The steepness of the line
The total distance between the two points
How far the line extends
02
Question 02/03
What does the Y-Intercept represent on a graph?
The rate of change
The point where the lines crosses the y-axis
The steepness of the graph
The point where the line crosses the x-axis
Question 03/03
How does y= mx compare to y=mx+b?
y=mx goes through the origin but y=mx+b is shifted
y=mx is steeper than y=mx+b
Both goes through the origin
The slope is different in both

Question 01/03
A worker earns $12 per hour. What is the equation for the total earnings, y, after, x, hours if they also get a $50 bonus?
y= 12x +50
y= 12x -50
y= 50x +12
y= 62x

y= 4x+2
y= 6x
y= 2x -4
y= 2x +4
04
Question 03/03
A phone company charges a $30 monthly fee plus $0.10 per text message sent. Which equation models this?
y= 30x +0.10
y= 0.10x +30
y= 0.10x -30
y= 30x -0.10x

Question 01/03
If a line has a slope of -2 and crosses the y-axis at (0,5), what is its equation?
y= -2x + 5
y= -2x -5
Question 02/03
Which equation represents a non-proportional relationship?
y= x-2
y= 2x
06
Question 03/03
What mistake is in the equation for a line with slope= 3 and y-intercept = -2: y= 3+2x
The equation is correct
The y-intercept should be 0
The slope should be negative
The slope and x-term should be flipped
