Question

Which equation is represented by the table?

x y (x, y)
0 –1 (0, –1)
1 4 (1, 4)
2 9 (2, 9)


A.
y = 3x + 3

B.
y = 5x – 1

C.
y = 3x – 4

D.
y = –3x + 3

Answer 1

Hey there! Let's find the equation, shall we?

Answer 2

ok

Answer 3

Do you know how to find the slope from 2 given points? :)

Answer 4

no, i should have paid more attention in math class huh?

Answer 5

Here's the formula:

\[\frac{ y_2-y_1 }{ x_2-x_1 }\]

where \[(x_1,y_1) ~and~(x_2,y_2)\] are the two points

Answer 6

You are given three points, you can choose any 2 points and you will get the same slope!

So which two points do want to choose?

Answer 7

um, B?
