y=-5x+3
200
Write an equation given the following points:
(2, 1) and (4, 3)
y-1=1(x-2) or y-3=1(x-4)
200
Every input has one output
or
every x has one y
What is a function?
200
all the x values in a function
What is domain?
200
All the y values in a function
What is range?
300
Write an example of a linear equation.
any equation written in y=mx+b form
example: y=4x+9 or y=3x

How can you tell if a graph is a function or not?
Use the vertical line test. If it passes the vertical line test, it is a function. If it does not pass, it is not a function.
300
How can you tell if a graph is discrete?
The points on the graph are not connected.
300
How can you tell if a graph is continuous?
All the points on the graph are connected
300
Write an example of a non-linear equation.
any equation that has an variable with an exponent
example: y=x2+3
400
How do I graph using slope intercept form? y=mx+b
Use my y-intercept as my first starting point and use my slope to go up and over to the right to find my next point.
400
How do I use point slope form to graph and equation?
Use the x,y in your equation as the starting point and use the slope to go up and over to the right to find your other point.
400
How can I find the graph of an equation in standard form? Ax+By = C
Plug in 0 for y and solve for x to get the x-intercept. That will be the first point. Plug in 0 for x and solve for y to get the y-intercept. That will be the second point. Then connect the points to make your graph.
400
How do I find the slope from a table?
See how much y is increasing by and see how much x is increasing by. Then divide the increase in y into the increase in x to find your slope.
400
What is the slope in this equation y=-3x+2
-3
500
How do I find the slope of a line from looking at a graph?
Pick two points on the graph and make a slope triangle to see what the height and base of the triangle is. The height over the base will be the slope.

A taxi charges a pick-up fee plus a charge per mile. Maria paid $5. 50 for a 3 mile ride. Tommy paid $10.25 for a 9 mile ride. What is the slope or rate of this situation?
The slope is .79 or 79cents per mile.
500
How can you tell if a graph is linear vs non-linear?
A linear graph has straight lines.
500
Given the following information, find the y intercept.
(2, 4) and m=3
y-intercept = -2
500
How can you tell whether or not a table represents a function?
Look at the two columns. If there are any numbers that are the same in the input column, then it is not a function.
