Straight line

Simple Graph of the straight line allowing you to change the 'Gradient' and 'Intercept' values using sliders. Analyse the Intercept (as the place where the line crosses the 'y-axis') by increasing and decreasing Val_c Analyse the influence of the gradient on the steepness of the line: What happens to the gradient as the line gets steeper? it changes from upward [left to right] to downard [left to right]?
