One line passes through the points (-7, 4) and (5,-4). Another line passes through points (-7, - 4) and
(2,2).
Are the lines parallel, perpendicular, or neither?

Neither

Step-by-step explanation:

Let's find the gradients of the two lines first.

Parallel lines have the same gradient and the product of the gradients of perpendicular lines is -1.

Gradient of 1st line

Gradient of the other line

Since the two gradients are not equal, the lines are not parallel to each other.

Product of the gradient

≠ -1

Thus, the 2 lines are not perpendicular to each other.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
