Question

What is the slope of the line passing through the following points: `( 0,4), (2,-5)`?

Answer 1

`"slope "=-9/2`

Explanation:

`"calculate the slope m using the "color(blue)"gradient formula"`

`•color(white)(x)m=(y_2-y_1)/(x_2-x_1)`

`"let "(x_1,y_1)=(0,4)" and "(x_2,y_2)=(2,-5)`

`rArrm=(-5-4)/(2-0)=(-9)/2=-9/2`
