Texas Instruments: Linear Functions: Slope With Grid
Students learn to impose a grid on a line to quantify the steepness of a line. They learn that slope is the ratio of vertical change divided by the horizontal change. They also learn that lines can have slope that are positive, zero,...

Texas Instruments: Linear Functions: Slope Using Coordinates
Students learn that the slope is ratio of change in y to the change in x. They find the slope of a line using the slope formula, and examine the characteristics of lines with positive, zero, negative, or non-defined slope.
