4 Slope of a LineNotice that this is the rate of change of y with respect to x.The units of the range variable go in the numerator and the units of the domain go in the denominatorNow, how would this look in function notation?
5 Definition of SlopeThe slope of the line is it’s measure of steepness. It measures the rate of change of the line. In all lines the slope is constant, it doesn’t change no matter where you are at on the line.

9 InterceptsWhere the graph crosses the x-axis is the x-intercept. It has coordinates (a,0).Where the graph crosses the y-axis is the y-intercept. It has coordinates (0,b).
