Write the equation of the line that passes through the points (4,-1) and (4,8). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.

x = 4

Step-by-step explanation:

Given the points (4, - 1) and (4, 8)

Note the x- coordinates are 4 in both cases.

This indicates the line passing through the points is vertical with equation

x = c

where c is the value of the x- coordinates the line passes through. In this case 4, thus

x = 4 ← equation of vertical line

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
