Plot the point that is symmetric to (−5,5) with respect to the y-axis.

Respect to the y axis

the y axis is the vertical (up and down) line

so reflecting across the y axis means that yo mulply x by -1

(x,y) reflected across the y axis turns to (-x,y)

s
(-5,5) turns to (-(-5),5)=(5,5)

the point is (5,5)

it is 5 units up and 5 units to the right of the origin (intersection of x and y axises)

5 units up and 5 units to the right of the origin

You can divide 3 divided by 4 and get 0.75
