<u>Algebra I</u>

  • Reading a Cartesian plane
  • Coordinates (x, y)
  • Slope Formula: \displaystyle m=\frac{y_2-y_1}{x_2-x_1}

Step-by-step explanation:

<u>Step 1: Define</u>

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

Point (0, 1)

Point (2, 2)

<u>Step 2: Identify</u>

x₁ = 0, y₁ = 1

x₂ = 2, y₂ = 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>

  1. Substitute in points/variables [Slope Formula]:                                            \displaystyle m=\frac{2-1}{2-0}
  2. [Slope] [Fraction] Subtract:                                                                              \displaystyle m=\frac{1}{2}

Answer:

Step-by-step explanation:

3. = 180 - 142

   = 38 angles on a straight line equal 180

4. =142 - vertically opposite

5. = 38 alternate angles, alternate with angle 1

6. = 142 - alternate angles

7. = 142 - corresponding angles, corresponding with angle 2

8. = 38 - vertically opposite

9. = 43 - corresponding to angle 7

10. = 137 - vertically opposite

11. = 180 - 137 = 43 - angles on a straight line equal 180 degrees

12. = 43 - vertically opposite to angle 6

13. = 43 - alternate to angle 6

14. = 137 alternate angles
