Question

Write an equation in standard form of the line passing through the given pair of points.

The line goes through the points ​(3​,4​) and ​(3​,1​)

What is the equation of the line?
A. x=3
B. y=4
C. Undefined
D. x+y=4

Answer 1

Answer: x = 3

If you picture the line, it goes through points that are on the same part of the x-axis, which means that it is a straight vertical line. Also, since it passes through 3 on the x-axis and does not touch the y-axis at all, you can only say that x = 3

Answer 2

(3,4)(3,1)

little tip.....if ur points have the same x value, which they do....the 3's, then it is a vertical line and is represented by x = a number. That number would be ur x values. So the equation for this line is x = 3. <==

if ur y values would have been the same, it would have been a horizontal line represented by y = a number...and that number would be the y values
