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

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (4, 1)

Point (0, 3)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

1. Substitute in points [Slope Formula]:                                                            $\displaystyle m=\frac{3-1}{0-4}$
2. [Fraction] Subtract:                                                                                         $\displaystyle m=\frac{2}{-4}$
3. [Fraction] Simplify:                                                                                          $\displaystyle m=\frac{-1}{2}$
