Question

line 1 contains (2, -4) and (0,2) Line 2 contains (-4,5) and (-1, 6) are the line parallel perpendicular or neuther? please help! thankss!

Answer 1

Calculate the slopes using

y-y1/x-x1 (pick whichever point you like to be (x,y)

Answer 2

slope of line 1 = (-4-2)/(2+4) =-1
slope of line 2 = 1
equation of line 1
y+4=x-2
y=x-6
equation of line 2

y+4=-x-2

y=-x-6
