Question

Find the slope of the line that passes through the points (2,-20) and (1,-20).

Answer 1

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

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

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

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

= - 20+20/ 1-2

= 0/-1

= 0

hope it helps

• Coordinates (x, y)
• Slope Formula:
  `\displaystyle m=(y_2-y_1)/(x_2-x_1)`

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=(-20+20)/(1-2)`
2. [Fraction] Subtract/Add:
   `\displaystyle m=(0)/(-1)`
3. [Fraction] Divide:
   `\displaystyle m=0`
