Plotting Straight Line Graphs using Intercept Method Math Review
math tutorials > plotting straight line graphs using intercept method tutorial
To plot a straight line you need only 2 points
The x-intercept is the point where the graph cuts the x-axis (x,0). The y-intercept is the point where the graph cuts the y-axis (0,y).
- To calculate the y-intercept, put x = 0.
- To calculate the x-intercept, put y = 0.
- Plot the 2 intercepts and join them with a straight line.
Graph intercept problems for you to try
1) x + y = 7
2) y = -x + 2
3) 2y + 3x = 6
