Question

m passes through points (1,5) and (3.5,7). Line n passes through points (4,7) and (7.5,10). Are lines m and n parallel? Explain.

Answer 1

No

Explanation:

parallel= same gradient

y2-y1/x2-x1= gradient

M: 7-5/3.5-1

=2/2.5

=0.8

N: 10-7/7.5-4

=3/3.5

=0.86 (2DP)

no, the gradients are not the same, so therefore the lines m and n are not parallel.

Hope this helps:)
