Answer:
The points lie on a vertical line
Step-by-step explanation:
given the points (1, 4 ) and (1, - 7 )
The x-coordinates of the points both equal 1
This indicates they lie on a vertical line with equation
x = c ( c is the value of the x- coordinates the line passes through.
given the x- coordinates are 1, then
The points lie on a vertical line with equation x = 1
