In a previous exercise, you graphed linear equations written in standard form using two ordered pairs that lie on the line. Another way to come up with two points that lie on the line is to solve for the intercepts. From the standard form of the line, Ax + By = C, the intercepts may be found using these formulas: x-intercept = C/A; y-intercept = C/B.
Directions:
1) Solve for the slope: -A/B. If the coefficient of y is 0, the slope is undefined.
2) Solve for the x-intercept: C/A; solve for the y-intercept: C/B
3) Enter the values in their respective boxes.
4) Move the

Which method do you find more convenient: using two ordered pairs or using the intercepts? Why?
