Question

Math help ??

Answer 1

What"s Your question?

Answer 2

I honestly don't know sorry

Answer 3

Slope-intercept form is y = mx + b, where m is your slope and b is your y intercept. With what you've already figured out, what part of the equation can we complete so far?

Answer 4

Y = Mx + 3 now what ?

Answer 5

To find m, we need to find the slope.

The slope is basically the change in y divided by the change in x between two points. Rise over run, as some may call it

Looking at the graph, the lowest point is at (0,2) and the highest point is at (10,20)

Would you know how to find the slope between these two points?

Answer 6

2/10 ?

Answer 7

no sorry -2/-10
Because 0 - 2 = -2 and 10 - 20 = -10

Answer 8

@FortyTheRapper

Answer 9

Not quite. What you did was y1-x1 divided y2-x2

For slope, it's y2-y1 divided by x2-x1

Try that one out. You'll end up with an improper fraction

Answer 10

-2/10 ???

Answer 11

So we got

(x,y)
(0,2) --- 1st coordinate, so x1 and y1
(10,20) ---- second coordinate, so x2 and y2

So for the first part of the formula, it's y2-y1

y2 is 20 and y1 is 2. See how I got that part?

Answer 12

yes so 20 - 2 ?

Answer 13

if thats what i have to answer 20 - 2 = 18

Answer 14

Right, that's finding the y part in \[\frac{ y }{ x }\]

Now we need to find the x part

Answer 15

10 - 0 right ?

Answer 16

Exactly

Answer 17

Making it \[\frac{ 18 }{ 10}\] as your slope. Now all you need to do is simplify it

Answer 18

9/5

Answer 19

Yep, that's m (your slope)!
