The equation y = 8x + 12, where x is the number of hours and y is the total cost, represents what the surf instructor charges for lessons. Use this information to describe how to draw the line on a graph.

Answer :

Plot a number of hours against total cost graph.
(1) by y=mx+c
The line with slope of 8 and y-intercept is 12.
The other way to plot a graph is put some integer into x to find out y, vice versa.For example when y=12,
x is equal to 0.
when y= 20,
x is equal to 1.
You can find out 3 point and join the line.
Finally the graph is finished.

Sample Answer: Use the rise/run strategy to draw the line. Start at the y-intercept (0, 12), and count 8 up and 1 to the right to the point (1, 20). Then, draw a line through the points. Test the point (3,36) in the equation y = 8x + 12 to verify that the line is correct.
