Asoftware 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?

y = (-3/7)x + 9 ( -1.5x − 3.5y = -31.5)

Step-by-step explanation:

Normally, there's a list of possible answers associated to this question, and the answer is usually in the form of  -1.5x − 3.5y = -31.5 (equivalent to  y = (-3/7)x + 9)

You forgot to provide the reference image which is essential to answer the question, but I managed to find it... and attach it to my answer.

In the given equation for AB, if we place the y term on the left and x term on the right, we see the slope of that line is 7/3 (y = (7x - 21.5)/3 ==> 7/3x).

We see on the image that the line PQ is perpendicular to AB.  That means that its slope is -3/7.

So, we have a slope  of -3/7 and we know it passes through point P (7,6), let's see if we can find the missing term.

y = (-3/7) x + b

6 = (-3/7) 7 + b

6 = -3 + b

b = 9

So the equation of the line forming the street PQ is y = (-3/7)x + 9

-1.5x − 3.5y = -31.5
