New cards
what is the y-intercept?
The point where a line intersects the y-axis.
2
New cards
What is y-intercept form?
y\=mx+b
3
New cards
What determines a positive or negative slope?
Whether the line in "running" up or downhill (always read left to right)
4
New cards
What determined an undefined slope?
When a line is completely vertical (ex. x\=-4)
5
New cards
What determines a slope of 0?
When a slope is completely horizontal with no "rise" (ex. y\=2)
6
New cards
What is the x-intercept?
The point where a line intersects the x-axis.
7
New cards
In the equation y\=mx+b, what is m?
The slope; the coefficient of X is always the slope
8
New cards
In the equation y\=mx+b, what is b?
The y-intercept
9
New cards
What are the three equations used to find slope?
y2-y1/x2-x1
change in y/change in x
rise/run
change in y/change in x
rise/run
