Question

What is the x-intercept of x = -5​

Answer 1

Answer:

(-5,0)

Step-by-step explanation:

The x-intercept of a line is a point at which the line intersects the x-axis. Any equation of a line that is written as "x = a number" is completely vertical.

That number, whatever it may be, represents the x-value of all the points the line intersects (they are all the same). However, the y-values are different. We know that the answer needs to be a point on the x-axis - and all points on the x-axis have a y-value of 0. Therefore, knowing these two pieces of information, the x-intercept must be (-5,0).
