The correct statement are the first and the second ======================================= The first statement: y = (-2/3) x - (13/3) slope = -2/3 and passing through (4,-7) because (-2/3) *4 - (13/3) = -7 the slope of the parallel line = -4/6 = -2/3 ============================================================ The second statement y = (-7/2) x - (5/2) slope = -7/2 and passing through (-3,8) because (-7/2) *-3 - (5/2) = 8 the slope of the perpendicular line = 2/7 the multiplication of the two slopes = -7/2 * 2/7 = -1 ============================================================
The third is false because the lines are parallel not perpendicular
the fourth is false because the lines are perpendicular not parallel
graph them and then see if they intersect(but if you notice that the coordss of the second line are all smaller than the coords of the first line, meaning that they wont be touching at all)
