EXPLANATION:

Perpendicular in this case means that the slope will be the negative reciprocal to the one given.

For example: 1/6 = -6 or 6 = -1/6

ANSWER:
-2

The line which crosses through L must have an intersect point with L to become perpendicular.

Gien slope is positive 1/2.

What is a straight line graph?

  • The graph follows a straight line equation shows a straight line graph.
  • equation of a straight line is  y=mx+cy represents vertical line y-axis.
  • x represents the horizontal line x-axis.    
  • m is the slope of the line

            slope(m)=tan∅=y axis/x axis.

  • c represents y-intercepts (it is the point at which the line cuts on the y-axis)

Straight line graphs show a linear relationship between the x and y values.
