Question

Find the slope of the line that passes through (26, 15) and (1, 86).

Answer 1

Answer:

-71/25

Step-by-step explanation:

We can use the slope formula when given two points

m = (y2-y1)/(x2-x1)

m = (86-15)/(1 -26)

   = 71/-25

  = -71/25

Answer 2

Answer:

$\displaystyle m = \frac{-71}{25}$

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

Step-by-step explanation:

Step 1: Define

Identify

Point (26, 15)

Point (1, 86)

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]:                                                              $\displaystyle m = \frac{86 - 15}{1 - 26}$
2. Subtract:                                                                                                            $\displaystyle m = \frac{71}{-25}$
