rate of change
Rate of change is a ratio of the amount of change in the output to the amount of change in the input.

If a graph has a rate of change that is the same between each box, or interval, it would be called a constant rate of change.
If it were to be put on a graph, it would be a straight, continuous line.
If the rate of change is different between each box, or interval, it would be varied, or variable.
If it were to be put on a graph, it would be several straight lines, not just one.
If the rate of change is equal then there is still a constant rate of change and it would be graphed as a straight line.

Slope
Slope of a line is the ratio of the change in y- values for a segment of the graph to the corresponding change in x-values.
The formula for finding slope is always m= y2- y1/ x2- x1.
The formula for finding slope is always m= y2- y1/ x2- x1.
Slope- intercept form is what is used to find the equation of the line.
Slope- intercept form is y= mx +b.
Slope- intercept form is y= mx +b.
Point- slope form is used to find a point in order to graph a line, when you already know the slope and the second point.
Point- slope is y - y1 = m( x - x1).
If y1 or x1 are negative, then you make the subtraction sign in the problem an addition sign.
Point- slope is y - y1 = m( x - x1).
If y1 or x1 are negative, then you make the subtraction sign in the problem an addition sign.
Standard form is used to find the distance of a point of a line.
Standard form is ax + by = c.
Standard form is ax + by = c.
Direct variation
Direct variation has the equation y = kx.
K is a nonzero constant, or the constant of variation.
K is a nonzero constant, or the constant of variation.
