What is the slope of the line that passes through (-4, 5) and (2, -3)?
vagabundo [1.1K]

Slope <em>m</em> has a form of,

m=\dfrac{\Delta{y}}{\Delta{x}}=\dfrac{y_2-y_1}{x_2-x_1}

We have points <em>A</em> and <em>B</em>,

A(x_1,y_1),B(x_2,y_2)\longrightarrow A(-4,5),B(2,-3)

Now insert the values in the slope formula,

m=\dfrac{-3-5}{2-(-4)}=\dfrac{-8}{6}=\boxed{-\dfrac{4}{3}}

The answer is A.

Hope this helps.
