Help! I’ll mark brainlest :(

A) y = 4

Step-by-step explanation:

Line AB is a vertical line, so a line perpendicular to it would have to be a horizontal line (perpendicular lines make an "x" shape with one another). Horizontal lines are written as y = ___ .

The perpendicular line also has to pass through the point (2,4). Points are written as (x, y). Therefore, the y-value in (2,4) is 4.

The perpendicular line has to be y=4 since it passes through both the Line AB and the given point.

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
