Question

Problem is attached in the picture.

Answer 1

solve both for y to make a y = mx + b form

Answer 2

perpendicular.
the slope of one line is the inverse of the other one

Answer 3

the "minus" signal doesnt matter. It only tells you if the line is rotated clockwise or counter clockwise

Answer 4

if both have the same slope, parallel... if the slopes are negative reciprocals of one another, then perpendicular.

Answer 5

y = mx + b and y = -(1/m)x + b the slopes are perpendicular.

Answer 6

the equations turn out to be....

Answer 7

y = (-3/4)x +6 .....and..... y = (4/3)x + 9...... so they are perpendicular

Answer 8

thanks for the medals ! ;) ha ha

Answer 9

NP.
