The equations of three lines are given below. line 1: 3y =2x+7 line 2: y=2/3x - 8 line 3: 6x-4y=6 for each pair of lines determine weather they are parallel, perpendicular, or neither. line 1 and line 2: line 1 and line 3: line 2 and line 3:

Solve for y for the second equation: y = 2/3x + 1

Both equations will cross the y axis at +1, but one will have a slope of 2/3, and one will be -2/3 slope.

A perpindicular line has the negative reciprocal of the slope, not just the negative.

its kind of blurry. can you put a clearer pic?

step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
