Miscellaneous
100
The steepness of a line that can be found using rise over run.
What is slope?
100

If the slope is increased, what happens to the line?

It is getting steeper.

100
What is the y-intercept of y = 3x+2, written as a point?
(0,2)
100
Why is slope intercept form better than standard form? y=mx+b instead of something like 5x-2y=9
You can pick out the slope and y-intercept right away.
100
What is the slope of a horizontal line? (Remember N or Z)
Zero
200
The point where a line crosses the y-axis.
What is the y-intercept?
200
What is the slope of y=7x+8
7
200
What is the y-intercept of y=5x, written as a point?
(0,0)
200
Convert the following to slope-intercept form: 2x+y=8
y = 8+2x
200
What is the slope of a vertical line? (Remember N or Z)
No slope- undefined
300
The point where the line crosses the x-axis.
What is the x-intercept?
300
Of the following, which has the steepest slope? y = 6x+9 y = 3x+20 y = -4x+8 y = -1x-9
y = 6x+9
300
What is the y-intercept of the line given, written as a point?
(0,-4)
300
Convert the following to slope-intercept form: 2x-2y=2
y = -1+x
300
What is the symbol > in words?
Greater than
400
The "perfect line," which has the equation y=x and y and x are always the same.
What is the parent function?
400
What happens when the slope is negative? What does the graph look like?
It decreases from left to right
400
What is the x-intercept of the graph, given as a point?
(-1.5,0)
400
Convert the following into slope-intercept form: 3y-6x=-9
y = -3+2x
400
If you graph a linear inequality and the line is dotted and below the line is shaded, what symbol was in the linear inequality?
<
500
The form of an equation where we can immediately pick out both the y-intercept and the slope.
What is slope-intercept form?
500
What kind of line has a slope of zero?
A horizontal line.
500
When given a table, how can you find the y-intercept?
Look at where x is zero.
500
Convert the following into slope-intercept form: 3x-3y=9
y = -3+1x
500
What is the graph of y ≥ 3x+2 going to look like (dotted or solid line? where is it shaded?)
shaded above, solid line.
