Question

medal + fan!!!!!The graph of following ordered pairs: 1,1 2,3 4,7 5,9




x y

3 7
8 17
10 21

Answer 1

You need y as function of x?

The formula is y=ax+b

Answer 2

You can find a and b if you know how to read the graph.

Answer 3

oops heres the question Does the graph represent the same equation as the table? Explain

Answer 4

What do you think?

Answer 5

no

Answer 6

Why?

Answer 7

cuz there not even the same numbers, I just wanted to make sure.....that I wasn't SOMEHOW being tricked!!

Answer 8

You could have been tricked, because the numbers need not be the same.
BUT: the same x's should come with the same y's, so the graph gives you x=4, y=7 and the table says x=3, y=7, so that can never be the same formula.

(I assume the formula should be that of a linear function...)

Answer 9

If the formula can be any function, I could imagine that both the graph and the table can have the same (more complicated) formula.

Answer 10

..... so the answer would be no, because the same X's should come with the same Y's

Answer 11

yes
same slope and

Answer 12

sorry no
y = 2x -1 is the equation for the graph
y = 2x + 1 is the equation from the table

Answer 13

Here are all the points in one graph (blue and red points)

Answer 14

You cannot fit them into one line...

Answer 15

ok
