Question

What is the slope of a line that passes through the points (-2, 3) and (4, -12)?Choices -3/2 -5/2 -2/5 -9/2

Answer 1

• B) - 5/2

--------------------------

To find the slope use the slope formula:

• 
  `m=\cfrac{y_2-y_1}{x_2-x_1}`, where,
  `x_1=-2,\ y_1=3,\ x_2=4,\ y_2=-12`

Substitute the coordinates into slope formula to get the slope:

• 
  `m=\cfrac{-12-3}{4-(-2)}=\cfrac{-15}{6}=-\cfrac{5}{2}`

The matching choice is B.
