Question

aravindg · Answer

Use the two point form or intercept form.

gokuporter · Answer

To find the slope?

pooja195 · Answer

Start by picking 2 points that are on the graph.

gokuporter · Answer

2 and 4?

pooja195 · Answer

Coordinates come in pairs
(x,y)

gokuporter · Answer

(2,4) (5,6)

pooja195 · Answer

None of those are points on the graph... 
|dw:1455077661883:dw|

pooja195 · Answer

Look at the dots those represent points

gokuporter · Answer

So I pick any of those 2 points and use the slope formula?

pooja195 · Answer

correct

gokuporter · Answer

Is it 1/2?

mathmale · Answer

I will arbitrarily pick a point for you to start with and ask you to pick another point on the graph:  Let my point be (-4,0).  Move to the right along the line and choose another point (trying to select one whose coordinates are integers).  Your choice?   ( x, y )

mathmale · Answer

Next, use the slope formula to find the slope of this straight line.

Next, insert the appropriate values of the slope (m) and the coordinates of one of these points into the point-slope formula for the equation of a straight line:$$y-y _{0}=m(x-x _{0})$$

mathmale · Answer

If you'd like for someone to tell you you're correct or not, please show how you obtained your result.  For example, what calculations led you to believe that the slope is 1/2?

pooja195 · Answer

1/2 is correct.
Two points:
0,2
2,3
3-2=1
2-0=2
I did it with different points  :P but still got the same answer

gokuporter · Answer

Thank you guys for the help. :)

gokuporter · Answer

So the y-intercept is 2 right?

pooja195 · Answer

Yes
the line is hitting +2 on the y axis

mathmale · Answer

Look at the graph again.  What are the coordinates of the point where the graph crosses the y-axis?

x = ?

y = ?

gokuporter · Answer

Why is it +2 and not just 2?

pooja195 · Answer

Same thing :P 
i meant it as a shorter version of positive 2

gokuporter · Answer

So 2 and +2 are the same? That's confusing.

pooja195 · Answer

+2 means 2

pooja195 · Answer

IT means positive 2 lol

gokuporter · Answer

Why would they have 2 of the same answers?

mathmale · Answer

A numeral such as 2, without either a + or a - sign, is automatically assumed to be positive.

pooja195 · Answer

The line is hitting 2 on the y axis therefore you are correct.
