Slope-intercept form is:
Where 'm' is the slope and 'b' is the y-intercept.
Only the first equation is in slope-intercept form, so that crosses out the first and last options. It also crosses out the second option since the first equation is already in slope-intercept form.
For the third option, let's convert the second equation into slope-intercept and see for ourselves:
Subtract 'x' to both sides:
Divide 3 to both sides:
So option C is correct.
