Jill converted the equation of the line 15x-4y=-2 into slope-intersept form and found the slope and y-intersept of the line as follows 15x-4y=-2
15x-4y-15x=-2-15x
-4y=-2-15x
-4y/-4 = -2-15x/-4
Y=-2/-4 = -15x/-4
Y= 1/2 - 15/4 x.
Y= - 15/4 x+1/2
Slope= - 15/4
Y-intersept = 1/2

What was her mistake?

A- She mixed up the slope and the y-intersept.
B- She got the sign of the slope wrong.
C- She got the sign of the y-intersept wrong.
D- She found the reciprocals of the slope and the y-intersept.
