Answer:
Step-by-step explanation:
For question 1: x = -4, y = -4; x = -2, y = -2; x = 0, y = 0; x = 2, y = 2; x = 4 y = 4.
Basically, just put the same numbers under each of them.
For question 2: I think the graph needs to be bigger, if Im not wrong.
Answer:
a) 1,4

Diameter-
a straight line passing from side to side through the center of a body or figure, especially a circle or sphere.
Multiply each term by a^2b^2:-
b^2y^2 + a^2x^2 = a^2b^2
subtract a^2x^2 from both sides
b^2y^2 = a^2b^2 - a^2x^2
Now divide both sides by b^2
y^2 = a^2 - a^2x^2 / b^2 = a^2 (1 - x^2/b^2)
take positive square root ( because y > 0)
y = a sqrt(1 - x^2/b^2)
