put this solution on YOUR website!Y varies directly as x is

where k is a constant of variation.
10. A student earns $0.65 for each mistake she finds in a text. Sketch the equation of direct variation.
A student=y
mistakes=x
k=$0.65
Your equation of variation is y=$0.65x
Plot a couple of points:
If the students finds 0 mistakes:
y=$0.65(0)
y=0
Plot (0,0)
If the student finds 1 mistake:
y=$0.65(1)
y=$0.65
Plot (1,.65) .65 is a little more than half way between 0 and 1.
Start your graph at 0 because the student can't find a negative mistake.
The vertical | amount represents the money the student earns and the horizontal line _ represents the amount of mistakes the students finds.
It should look like this:

Happy Calculating!!!
