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 1.5 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 y = mx + b.
y = 1.5x + 0.5
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 x and evaluate for the value of y.
