Graph a Linear Equation
Problem Statement:
Run the program and enter values for the slope, y-intercept, and starting and ending x-values for the linear equation. Observe how changing the slope and y-intercept change the graph. Graph a line that passes through the points (6, -6) and (-6, 12) from x = -12 to x = 10.
