Question

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

Answer 1

Answer:

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 = $\frac{-4-5}{0-2}$ = $\frac{-9}{-2}$ = $\frac{9}{2}$ → a

Answer 2

Answer:

a) 9/2

Step-by-step explanation:

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

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

$m=\dfrac{-4-5}{0-2}=\dfrac{-9}{-2}=\dfrac{9}{2}$
