Document Summary
Rate of change the relationship between two changing quantities, also known as slope (change in y over change in x) Linear equation equation that models a linear function, these equations form a straight line and have a highest power of one. Direct variation/proportional reasoning a relationship where as one variable goes up so does the other variable and a relationship that can be represented by the function y = kx, where k does not equal zero. Inverse variation/non proportional reasoning a relationship where as one variable increases, the other variable decreases. Slope the rate of change of the vertical change (the rise) to the horizontal change (the run) of a line, also known as the steepness of a line. Ax + by = c where a, b, and c are real numbers and a and b are both not zero x-intercept where a graph crosses the x-axis y-intercept where a graph crosses the y-axis.
