The point $(21, 32)$ is on a line with slope $1.5$.   

1. Write the equation of the line.

   Hint (a):

   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.

   More Help (a):

   Look at the graph to find the y-intercept and use it along with the given slope to complete the equation $y = mx + b$.

   Answer (a):

   $y = 1.5x + 0.5$

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

• Help (b):

  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 $y$.
