Write the slope-intercept form of the equation for the line. a. y= -3x - 1 b. y= 1/3x - 1 c. y= 3x - 1 d. y= 1/3x + 1 (picture is shown below)

The answer is C, you can tell because the b=-1, so that eliminates d, then you know the slope is positive because of the direction it goes, so that eliminates a. Then if you look at the slope, it goes up 3 over 1, so that makes the answer C.
Hope this helps
