Question 101 points)which equation in slope-intercept form represents the line that passes through (5, 1) and(-4,7)

In the xy-plane, if the parabola with equation passes through the point (-1, -1), which of the following must be true?

Which statements about the system are true? check all that apply. y =1/3 x – 4 3y – x = –7 the system has one solution. the system consists of parallel lines. both lines have the same slope. both lines have the same y–intercept. the equations represent the same line. the lines intersect.
