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 = - 2. 15 x minus 4 y minus 15 x = - 2 minus 15 x. - 4 y = - 2 minus 15 x. - 4 y Over - 4 = - 2 minus 15 x Over - 4 Y = - 2 Over - 4 minus 15 x Over - 4. y = one-half minus 15 Over 4 x. y = - 15 Over 4x + one-half. slope = - 15 Over 4. 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.
