Question

what is the equation of a vertical line passing through the point (3, −5)? a. y=-5 b. x=-5 c. y=3 d. x=3

Answer 1

VUX = vertical line, undefined slope, represented by x = a number.
so look at ur points (3,-5)....and a vertical line is represented by x = a number...so in ur points, the x value is 3, therefore, ur equation is :
x = 3......x will always be 3 no matter what y is.
