Answer:

Answers are included below with explanation on how to graph

Explanation:

7. Original: y= 1/3x Perpendicular: -3x

In the original graph given starting on the y-intercept (0,6) you go up 1 unit and to the right 3 units making your slope 1/3 so in order to find the perpendicular slope you must flip your slope 1/3 to be 3 and then change your sign from positive 1/3 to be negative 3. I'm assuming Point A is your y-intercept so you would start on (0,6) and go down 3 units and to the right 1 unit.

8. Original: y= -2x Perpendicular: 1/2x

In the original graph given starting on the y-intercept (0,-5) you go down 2 units and to the right 1 unit making your slope -2 so in order to find the perpendicular slope you must flip your slope -2 to be -1/2 and then change your sign from negative 2 to be positive 1/2. So you start at Point A (0,-5) and go up 1 unit and to the right 2 units.

9. Original: y= 0x Perpendicular: Undefined

In the original graph given there is no slope because the graph shows a horizontal line meaning that the slope is equal to 0 so in order to find the perpendicular slope you must flip the line to be a vertical line making your new slope undefined. So you start at Point A (0,3) and make a line going straight up and down.

10. Original: y= 1x Perpendicular: -1x

In the original graph given starting on the y-intercept (0,2) you go up 1 unit and to the right 1 unit making your slope 1 so in order to find the perpendicular slope you must flip your slope 1 to be 1/1=1 and then change your sign from positive 1 to be negative 1/1= -1. So you start at Point A (0,2) and go down 1 unit and to the right 1 unit.

I hope this helped!

Answer:

slope = 0

x = 1

Explanation:

9. the original line is y = 3

so the perpendicular line will be parallel to y axis

and for it to go through A(-1,-5) then x = -1

The x‐axis or any line parallel to the x‐axis has a slope of zero.
