Algebra I

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

Step-by-step explanation:

Step 1: Define

Point (2, -20)

Point (1, -20)

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]:                                                             $\displaystyle m=\frac{-20+20}{1-2}$
2. [Fraction] Subtract/Add:                                                                                    $\displaystyle m=\frac{0}{-1}$
3. [Fraction] Divide:                                                                                               $\displaystyle m=0$

Answer 2

Answer:

(x', y') =(2, - 20)

(x",y") =(1, - 20)

slope = y"-y'/x" - x'

= - 20-(-20)/1-2

= - 20+20/ 1-2

= 0/-1

= 0
