<u>Algebra I</u>

  • Terms/Coefficients

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

2(x + -5) + x = x + (-6)

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. [Distributive Property] Distribute 2:                                                                 2x - 10 + x = x - 6
  2. [Addition] Combine like terms (x):                                                                   3x - 10 = x - 6
  3. [Subtraction Property of Equality] Subtract <em>x</em> on both sides:                         2x - 10 = -6
  4. [Addition Property of Equality] Add 10 on both sides:                                   2x = 4
  5. [Division Property of Equality] Divide 2 on both sides:                                  x = 2

Answer:

1/4

Step-by-step explanation:

To find the slope of a line from two points we use

m = (y2-y1)/(x2-x1)

m = (3-2)/ (3--1)

   = (3-2)/(3+1)

  =1/4
