  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

<u>Algebra I</u>

  • Coordinates (x, y)
  • Slope Formula: \displaystyle m = \frac{y_2-y_1}{x_2-x_1}
  • Perpendicular lines are the negative reciprocal of the given line

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

Point G(-2, 3)

Point H(1, -2)

<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>

<em />

<em>Line GH</em>

  1. Substitute in points [Slope Formula]:                                                              \displaystyle m = \frac{-2-3}{1--2}
  2. [Fraction] Subtract:                                                                                           \displaystyle m = \frac{-5}{3}

<em>Perpendicular line</em>

  1. Negative:                                                                                                           \displaystyle m = \frac{5}{3}
  2. Reciprocate:                                                                                                      \displaystyle m = \frac{3}{5}

<span>
The ten's digit of a two digit number is 1 more than 4 times the units' digit.
</span>x = 4y + 1

<span>63 is subtracted from the number, the order of the digits is reversed
</span>10x + y - 63 = 10y + x
9x - 9y = 63

x = 4y + 1 ------------ (1)
9x - 9y = 63  ---------- (2)

Sub (1) into (2)
9(4y + 1) - 9y = 63
36y + 9 - 9y = 63
27y = 63 - 9
27y = 54
y = 2 ------- sub into (1)

x = 4(2) + 1 = 9

x = 9, y = 2
The number is 92
