For what value of b will the line joining points p and q be parallel to the y-axis p(5b-1,8) q(9,-7)

The value of b would have to be 2.

Step-by-step explanation:

In order to find this value, we need to note that in order for this line to be parallel to the y-axis, the x values must be equal. So we can set the variable x value in the first ordered pair equal to the x value in the second.

5b - 1 = 9

5b = 10

b = 2

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450
