  • Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Find points from chart.</em>

Point (2, 0)

Point (3, 0)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>.  Rate of change and slope are identical.

  1. Substitute [SF]:                     m=\frac{0-0}{3-2}
  2. Subtract:                               m=\frac{0}{1}
  3. Divide:                                  m=0

Goryan [66]

Well, that's incorrect because according to the Order of Operation [GEMS\BOMDAS\PEMDAS etc.], that -7 has to be distributed amongst all the other terms in parentheses. Besides, you did the wrong operation when you inserted that subtraction symbol in substitution of the parentheses, which means to MULTIPLY. So, the order goes as follows:

12 - 7[72]

-504 + 12 = -492 [OR 12 - 504]

-492 is your answer. You get it now?

What does a proportion look like?
AURORKA [14]

A proportion looks like this:

a\div b = c\div d

It means that the quantity a,b,c and d are in the same proportion: the ratio between a and b is the same ratio between c and d.

They are particularly useful in situation when you have an example given, and you want to extrapolate the relationship for another couple.

For example, you can think of the following problem: "Five apples cost 2 dollars. How much will 8 apples cost?"

You can build the proportion

5\div 2 = 8\div x

And then solve it for x:

\dfrac{5}{2}=\dfrac{8}{x} \iff 5x=16 \iff x = \dfrac{16}{5} = 3.2
