After 3x - y = 7 is put in slope intercept form, the slope and intercept are:
a. m = 3, b = 7
b. m = -3, b = -7
c. m = 3, b = -7
d. m = -3, b = 7

Slope-intercept form is simply y=mx +b

your equation is 3x -y = 7
rearranging that to y = mx +b makes it look like this:
- y = -3x +7
y =3x -7

making m =3 and b=-7, so your answer is C
