Question

Anyone good at eliminating parameters?

Answer 1

x = t2 + 3, y = t2 - 2

Answer 2

Take the first equation and solve for t^2 (by subtracting 3 from both sides).

Take that expression for t^2 and put that into equation #2. You'll end up with an equation in slope-intercept form, which is what you want here.

Answer 3

All good now, @crazyheart08 ?

Answer 4

could you write out what your talking about so i can see it? cause right now im still confused

Answer 5

Try subtracting 3 from both sides of equation #1. Write that out here in Openstudy.

Answer 6

x=t^2,y=t^2-5

Answer 7

? @tcarroll010

Answer 8

Just concentrate on equation #1 for now. Forget about equation #2. As for equation #1, it looks like you subtracted 3 from the right side but not from the left. You have to subtract 3 from both sides to preserve the equality. Now, give it another go. And just equation #1.

Answer 9

oh sorry i was confused..
x=t^2+3
-3 -3
x-3=t^2

Answer 10

Good! You now have an expression for t^2 which is the left side of your equation, and that is "x - 3". You take that "x - 3" and you put that into equation #2 where you see t^2 there.

Answer 11

oh okay :)
y=x-3-2
y=x-5

Answer 12

Good job! You got it!

Answer 13

thats it ? :D

Answer 14

Yep! That's all there is to it!

Answer 15

Thank you so much!! i get it now :)

Answer 16

uw! Good luck to you in all of your studies and thx for the recognition! @crazyheart08
