A graphed line passes through pair of points. Use the slope formula to find the slope of the line.

Question

(2, 4) and (1, 7)

Question 1 options:

-4

-2

-3

-5

Answer 1

The slope formula is given by:
m = (y₂ - y₁) / (x₂ - x₁)

Let's substitute the values in the formula:

m = (7 - 4) / (1 - 2)
m = 3 / -1
m = -3

Therefore, the slope of the line passing through the points (2, 4) and (1, 7) is -3.

Answer: -3
