Determine whether wz and yz are parallel, perpendicular, or neither.

w(–4, 5), x(8, –1), y(6, –2), z(1, –7)

question 15 options:

perpendicular

neither

parallel

  neither

Step-by-step explanation:

WZ and YZ have a point in common (Z), so cannot be parallel. They would be perpendicular if they had slopes that were negative reciprocals of each other, but they do not.

The lines are neither parallel nor perpendicular.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
