rise/run
What is the equation typed into your Desmos calculator that is used to find slope (m) and y-intercept (b)?
y1~mx1+b
Ax + By = C
x1; y1
y=mx + b
What does (m) and (b) represent in the slope-intercept form formula: y = mx + b?
(m) is the rise; (b) is the run
(m) is the slope and (b) is the y-intercept
(m) is the y-intercept and (b) is the slope
(m) is multiplication and (b) is subtraction
What does the slope (m) tell you?
Slope tells you how far to go.
Slope shows the movement of the graph.
Slope tells you where to start.
Slope shows how far you have come.
What does the y-intercept (b) tell you?
The y-intercept is the initial or beginning value of the graph.
The y-intercept shows where to cross the line.
The y-intercept is the first number at the origin.
The y-intercept tells the movement of the graph.

A local fair charges an entry fee as well as a fee for each ride ticket purchased at the fair. The equation y = 3x + 15 can be used to determine the amount of money a person will spend at the fair. What do the numbers 3 and 15 represent in terms of the money spent at the local fair?
The 3 represents the cost per ticket, and the 15 represents the entry fee.
The 3 represent the entry fee, and the 15 represents the cost per ticket.
The 3 represents the entry fee, and the 15 represents the total amount paid.
The 3 represents the cost per ticket, and the 15 represents the total amount paid.
What type of function does the equation y = 14(x - 2) represent?
cubic
nonlinear
quadratic
linear
Is the relation a function? Why?
Yes, because the x-value 11 is paired with two y-values.
Yes, because each x-value is paired with only one y-value.
No, because the x-value 11 is paired with two y-values.
No, because each x-value is paired with only one y-value.
