Jill converted the equation of the line 15 x minus 14 y = negative 2 into slope-intercept form and found the slope and y-intercept of the line as follows.

15 x minus 14 y = negative 2. 15 x minus 4 y minus 15 x = negative 2 minus 15 x. negative 4 y = negative 2 minus 15 x. StartFraction negative 4 y Over negative 4 EndFraction = StartFraction negative 2 minus 15 x Over negative 4 EndFraction. Y = StartFraction negative 2 Over negative 4 EndFraction minus StartFraction 15 x Over negative 4 EndFraction. y = one-half minus StartFraction 15 Over 4 EndFraction x. y = negative StartFraction 15 Over 4 EndFraction x + one-half. slope = negative StartFraction 15 Over 4 EndFraction. y-intercept = one-half.

What was her mistake?
She mixed up the slope and the y-intercept.
She got the sign of the slope wrong.
She got the sign of the y-intercept wrong.
She found the reciprocals of the slope and the y-intercept.
