Question

Write an equation of a line that passes through the point (-2,3) and is perpendicular to

the line x = 4

Answer 1

y = 3

Explanation:

x = 4 has an undefined slope meaning on a graph the line is vertical. In order to form a line perpendicular to this, we need a line with zero slope (horizontal line). We need to look strictly at the y coordinate to help determine the equation. In this case, we have a y coordinate of 3. Therefore, the equation will be y = 3.
