What is the slope of the line passing through the points (2, 5) and (0, –4)? a)9/2 b)-2/9 c)-9/2 d)2/9

Step-by-step explanation:

The formula of a slope:

We have the points (2, 5) and (0, -4). Substitute:

a

Step-by-step explanation:

To calculate the slope m use the slope formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (2, 5) and (x₂, y₂ ) = (0, - 4)

m = = = → a

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
