For what value of x will the line passing through the following pairs of points be vertical? a(x, 3) and b(3, 5)

answer:

x = 3

step-by-step explanation:

plot the given point b(3,5) and a vertical line through it:

next draw several possibilities for a(x,3), for instance

a(-4,3), a(-1,3), a(1,3), and a(5,3)

draw a line through them

now you can see that the only value of x is the value where the

blue line crosses the green vertical line, which is at a(3,3)
