B) y = -2x
when x = a
y = -2a
when x= 2a
y = -2(2a) = -4a
Answer: 3/5
Step-by-step explanation:
Answer:
Step-by-step explanation:
x^2/100 + y^2/25=1 -----(1)
Since 25<100
Hence the above equation is of the form x^2/a^2+ y^2/b^2=1-------(2)
Comparing (1) and (2)
a^2=100
a=10
Major axis=2a=20
C=(b,0) therefore you'll have to add the coordinates AC and BD
