using the coordinate plane shown below 1/3 point is plotted five units to the right of -4, for where should a four point be plan
Mrac [35]

we know that

the fourth point is plotted 5 units to the right of (-4,4)

so

the coordinate x of the fourth point is equal to

-4+5=1

the y-coordinate of the fourth point is the same y coordinate of (-4,4)

therefore

the coordinates of the fourth point is (1,4)
