Question

complete the following: 1. Find the locus of points whose: (a) ordinate saquare decressed by the square of the abscissa is the sum of the coordinates

Answer 1

P(x,y) is the coordinate point of the locus

ordinate is y

abscissa is x

Following the sentence we have

ordinate square y^2

decreased means subtract

square of the abscissa x^2

is means equal

the sum of the coordinates x+y

`y^2-x^2=x+y`
