Rate of Change
Question | Answer |
---|---|
direct variation | when two variables are related in such a way that the ratio of their values always remain the same |
negative slope | if the line goes down and to the right on a graph |
no/zero slope | (y = #) is a horizontal line because there is no change in the y value |
rate of change | tells how fast one variable changes compared with the other |
slope (positive/negative) | A measure of steepness of a straight line; graphically positive goes up and to the right; graphically negative goes down and to the right |
undefined slope | (x = #) is vertical line because there is 0 change in the x value |
y-intercept | where the line or parabola crosses the y-axis |
_x | indicates change in the domain |
_y | indicates change in the vertical axis |
