Question

A software designer is mapping the streets for a new racing game. All of the streets are depicted as either perpendicular or parallel lines. The equation of the lane passing through A and B is -7x + 3y = -21.5. What is the equation of the central street PQ?


-3x + 4y = 3



-1.5x − 3.5y = -31.5



2x + y = 20



-2.25x + y = -9.75

Answer 1

You need two things to write the equation of the line PQ:
Its slope (which could be calculated from the perpendicular line AB as the result of multiplication of their slopes will be -1)
and
one point on that line (which is (7,6))

Answer 2

Then you ought to use this form to get the line equation:
\[\frac{ y-y_z }{ x-x_1 }=m\]
where \[(x_1,y_1)\] is the point on the line.

Answer 3

Could you proceed with me?

Answer 4

yes

Answer 5

soooo how do we figure this out sorry i really suck at math :(

Answer 6

What is the slop of the line AB?

Answer 7

2/1

Answer 8

Do you know how to get it?

Answer 9

What is the slope of the line
\[-7x+3y=-21.5\]?

Answer 10

Hey
