Im so confused The question: The graph shows the amount of drink mix that was added to water at different intervals. What is the equation of the line in slope-intercept form, that represents this situation? The graph: http://gyazo.com/a01fa44eee68f8db75008baca1f1024d

sammixboo · Answer

slope-intercept form is y = mx + b

Where m = slope and b = y intercept

sammixboo · Answer

Do you know how to find the slope of this line on the graph?

anonymous · Answer

No I dont sadly

khalilforthewin · Answer

you need to know how to do that to answer this question

anonymous · Answer

Is it rise over run?

khalilforthewin · Answer

yea

sammixboo · Answer

Take a loook http://www.coolmath.com/precalculus-review-calculus-intro/precalculus-algebra/01-graphing-slopes-of-lines-01 And yes :)

sammixboo · Answer

After you find the slope, you plug that where m is in the slope-intercept formula y = mx + b

anonymous · Answer

Well I understand that but there are no points

khalilforthewin · Answer

If you do rise over run you you plug that in to the formula y=mx+b

sammixboo · Answer

You make your own points that lie on the line

anonymous · Answer

Its still confusing

sammixboo · Answer

Ok so let's choose these two points http://prntscr.com/6ksotk

anonymous · Answer

Ok

sammixboo · Answer

Can you find the slope given those two points?

Any points you choose, the slope will always be the same, just letting you know.

anonymous · Answer

(4,3) and (6,4) 
But if you do rise over run wouldnt it be run is 2 and rise is 2?

anonymous · Answer

y2 - y1 over x2 - x1
4 - 3 over 6 - 4 
1/2 correct?
