Question | Answer |
---|---|
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 or 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 |
direct variation | when two variables are related in such a way that the ratio of their values always remain the same |
starting point | the value of the function when time equals zero |
rate | a ratio that compares two quantities measured in different units |
nth term | any term in a sequence or pattern |
independent variable | the input variable whose value in a function affects the output variable (x) |
trend | a general direction either upward or downward |
constant | a term that does not contain a variable. (In 3x + 4, the 4 is a constant) |
constant rate of change | the rate of change in a linear relationship |
