If you have any trouble on a math problem and cant find it on quizlet i recommend two sites one is Mathway.com you enter your problem and it ask you how you want it solved and shows you how to solve it you can even give it corrdinates an it will generate a graph with them. The other site is Brainly.com you can search your question and it will either pop up with the same question from other users with an answer or you can ask it yourself.

Slope is known as the run over the rise.
- 4/5
What is the slope of the line shown on the graph
7
What is the x -intercept of the graph y = 2 x - 14?
4
What is the y -intercept of the equation 2 x + 3 y = 12?
x y -2 4 -1 2 0 0 1 2 2 4
What table of values goes with the equation y = |-2 x |?
True, remember non-liner means no line
When non-linear equations are graphed, they do not have straight lines.
Y axes point is 4 x axes point is -2
Which graph has an x -intercept of -2 and a y -intercept of 4?
-2
What is the slope of a line that passes through the points (-2, 4) and (-6, 12)?
False
The ordered pair of the x -intercept has a zero for the x -value.
True
The y -intercept is where a line crosses the y -axis.
y = 3 x + 4
What is the equation of a line that passes through points (0, 4) and (-4, -8)?
