The lines shown in the figure below are A. parallel
B. Perpendicular
C. Neither parallel nor perpendicular
D. Both parallel and perpendicular

A. Parallel

Step-by-step explanation:

Parallel lines are two lines that never intersect and will never intersect. In equations, this will mean the slopes will be the same while the y-intersect is different. They are not perpendicular because perpendicular lines will intersect at a right angle, and these lines never intersect.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
