A line L1 has a slope of (-2/7). State whether the line that passes through (3, -4) and (-4, -2) is parallel or perpendicular to line L1 .

Question

please help me

Answer 1

parallel lines have the same slope

find the slope of the line that passes through (3,-4) and (-4,-2)

slope=rise/run

slope=[-4-(-2)]/[3-(-4)]

slope=(-4+2)/(3+4)

slope=-2/7

the lines have the same slope so therefore they are parallel
