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.
1 answer:
Answer:
No
Step-by-step 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:)
