Question

Tell whether the lines for each pair of equations are parallel, perpendicular, or neither
y=-7/8x – 1  and  32x – 28y = –36

karatechopper · Answer

neither

anonymous · Answer

for perpendicular lines the slopes would multiply to give -1 and for parallel lines the slopes will be equal

anonymous · Answer

they are perpendicular

y=-7/8x-1      32x-28y=-36
                        y=8/7x +9/7

mulitply the slopes   -7/8 x 8/7
                          =-1

yea as Alisha22 says we have to find both the slopes.

in the first equation of the line we can see it is -7/8 comparing the equ. to y=mx+c

in the second 1 we have the sleope by rearranging

28y=32x+36

therefore y=8/7x+36/28

so slope is 8/7

the product is -1

so they are perpendicular to each other
