Question

if the line is perpandicular to the y axis , what is it throught the point (-4,-2). what is the slope of the line

Answer 1

Answer:

y=-2

Step-by-step explanation:

The y-axis is a vertical line that has a slope which is undefined. This means it has no m value. The equation of the y-axis is the form x=0. For a line to be perpendicular to a vertical line, it must be a horizontal line like the x-axis. Horizontal lines have a slope of 0 and the x-axis equation has the form y=0.

This line must also be horizontal and the line must be y= a number. The line needs to cross through (-4,-2). Then it must be y= -2 which is a horizontal line through -2 on the y-axis and every point with -2 as the y-coordinate including (-4,-2).
