Question

Question 5: What is the equation of the line parallel to x = 7, passing through the point (-4, 1)?

A. X = -4
B. X = 1
C. Y = -4
D. Y = 1

Answer 1

(A) x= -4

Explanation:

The question requires you to find the equation of the line parallel to x=7

Line x=7 is a vertical line crossing the x-axis at x=7

A vertical line has undefined slope, no slope

However, parallel lines are those that do not meet and has the same slope. This means you should expect that the equation required should also have an undefined slope, slope of zero.

The line will pass through point (-4,1) and be a vertical line.

The equation of the line will be: x= -4
