Question

R(55, -75) W(-15,-40)

Find the slope

Answer 1

m = -0.5

Explanation:

Given that, ( Coordinates of a line )

( 55, - 75 ) ⇒ ( x₁ , y₁ )

( - 15 , - 40 ) ⇒ ( x₂ , y₂ )

The formula to find the slope of a line is:

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

Let us find it now.

`\sf m =(y_1-y_2)/(x_1-x_2) \\\\\sf m =(-75-(-40))/(55-(-15)) \\\\\sf m =(-75+40)/(55+15) \\\\\sf m =(-35)/(70) \\\\m = -0.5`

Answer 2

- 1/2

Explanation:

We can use the slope formula to find the slope.

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

= ( -40 - -75)/(-15 - 55)

= (-40+75)/( -15-55)

=35/-70

=- 1/2
