Question

(g) distance from the x-axis is equal to the distance to the y-axis.

Answer 1

Part a

Remember that the ordinate is the y-coordinate and the abscisa is the x-coordinate

so

(x, 2x+1)

y=2x+1

Part b

`((1)/(2)y^2,y)`

x=(1/2)y^2

Part c

x^2+y^2=25

Part e

y=2

Part f

x=7

Part g

x=y

Part h

`\sqrt[\square]{x^2+y^2}=5`

Part i

`\sqrt[\square]{(x-2)^2+(y-3)^2}=5`
