Question

What is the slope of the line passing through (9,4) and (3,9)

Answer 1

`\sf m=-(5)/(6)`

Explanation:

The formula to find the slope is :

`\sf m=(y_1-y_2)/(x_1-x_2)`

For that, let us use the given two coordinates.

( 9 , 4 ) ⇒ ( x₁ , y₁ )

( 3 , 9 ) ⇒ ( x₂ , y₂ )

Let us solve it now.

`\sf m=(y_1-y_2)/(x_1-x_2)\\\\\sf m=(4-9)/(9-3)\\\\\sf m=-(5)/(6)`
