I need help urgent plz someone help me solved this problem! Can someone plz help I’m giving you 10 points! I need help plz help
poizon [28]

Answer: Delete the point (0, 4)

<u>Step-by-step explanation:</u>

Your line for y = (1/3)x + 4 is correct.

                             m=1/3   b=4

Start at (0, 4) and draw a line through a point up 1 and 3 to the right (3, 5).

Your line for x = 6 is correct.

A vertical line through (6, 0), (6, 1), (6, 2), ...

Your point for (6, 6) is correct.

                    x=6, y=6

Your error is that you used the dot tool to plot a point for (0, 4). You DO need this point to create the line y = (1/3)x + 4, however the instructions do not state to mark this coordinate with a dot.

Janet is three years older than her sister Julie.Janets brother is 8 years younger Than Her sister Julie .the sum of all of thei
slavikrds [6]

x + x + 3 + x - 8

3x - 5 = 55

3x = 60, x = 20

Since we put Julie as x, we put Janet at x + 3, and the brother is x - 8 (8 years younger)

Julie is 20

Janet (x + 3) = (20 + 3) = 23

Brother(x - 8) = (20 - 8) = 12
