The point is on a line with slope .   

  1. Write the equation of the line.

    One possible way to solve this problem is to plot the point and use the slope to draw the line.
    Convert to a fraction and remember that the numerator is the rise and the denominator is the run.

    Look at the graph to find the y-intercept and use it along with the given slope to complete the equation .

  2. What are the coordinates of another point on the line?

  • To find a third point on the line, either find one on your graph, or substitute any number for and evaluate for the value of .
