Answer:

Associative

Step-by-step explanation:

The associative property of addition states that you can add numbers however they are grouped inside parentheses.

It doesn't matter where you put the parentheses. You will always get the same answer.

For example,

$\begin{array}{rcl}(5 + 3) + 7 & = & 5 + (3 + 7)\\8 + 7& = & 5 + 10\\15 & = & 15\\\end{array}$

Phoenix [80]

Answer:

Equation of a line is y = mx + c

Where m is the slope

c is the y intercept

Equation of the line using point

( 1 , - 4) and slope 5/2 is

$y + 4 = \frac{5}{2} (x - 1) \\ \\ y + 4 = \frac{5}{2} x - \frac{5}{2} \\ \\ y = \frac{5}{2} x - \frac{5}{2} - 4 \\ \\ \\ y = \frac{5}{2} x - \frac{13}{2}$
