Question

1. Are fand g perpendicular? Use the slopes of the lines to justify your answer.

2. Are fand h perpendicular? Use the slopes of the lines to justify your answer.
3. Are g and h perpendicular? Use the slopes of the lines to justify your answer.

(Had to edit a bit sense it couldn’t fit on my screen)

Answer 1

Slope of f = 2/3

Slope of g = -3/2

Slope of h = -2/3

1) Yes, f and g are perpendicular since

2/3 × -3/2 = -1.

2) No, f and h are not perpendicular since

2/3 × -2/3 ≠ -1.

3) No, g and h are not perpendicular since

-3/2 × -2/3 ≠ -1.
