Straight Line Graph (Slope-Intercept Equation)




 

Explore the properties of a straight line graph

The equation of the straight line graph in slope-intercept form is y = mx + c.

The following activity allows you to explore the properties of a straight line graph.
Move the m and c slider bars to explore how it affects the slope, m and y-intercept, c, of the graph. Look at
  • the effects of changing the slope, m
  • the effects of changing the y-intercept, c
  • the effects of a positive and a negative value of the slope, m
  • the effects of a positive and negative value of the y-intercept, c
  • how to create a horizontal line by making the slope, m = 0
