Question

Write the equation for this graph in the form of y = mx + b.

Answer 1

For the equation y=mx+b, m represents the slope while b represents the y intercept. Do you know how to find the slope and y intercept?

Answer 2

i dont think so

Answer 3

For the y intercept, where does the line cross the y axis?

Answer 4

(2,1)

Answer 5

On that point of the line is it touching the y axis?

Answer 6

no ,0?

Answer 7

(2,4)

Answer 8

Yes the y intercept is 0 because that is where the line touches it.

Answer 9

At any other point besides (0,0) the line doesn't cross the y axis. Understand?

Answer 10

ok

Answer 11

so i would have to put that in the problem?

Answer 12

So the y intercept represents the "b" part of the equation. So far we y=mx+0 because the y intercept is 0. Now all we have left is m which is the slope. Do you have any guesses for the slope?

Answer 13

(10,5)

Answer 14

The slope isn't a point. The slope is a number that represents the change from 1 point to another.

Answer 15

2

Answer 16

That is correct, the slope is 2. Now can you tell me your final answer for this problem?

Answer 17

y=2x+0

Answer 18

Correct.

Answer 19

thank you.
