Question 104397
L1 through (–4, –7) and (1, 3)
L2 through (2, 6) and (4, 10)
You need to find the slope of each;
point-slope form;
L1={{{m=(3-(-7))/(1-(-4))}}}
L1={{{m=10/(5)}}}
L1={{{m=2}}}
L2={{{m=(10-6)/(4-2)}}}
L2={{{m=4/2}}}
L2={{{m=2}}}
Parallel lines have the same slope, perpendicular lines, slopes are negative reciprocals. These lines are Parallel.
