Step-by-step explanation: To find n, plug all the given information into the slope formula, which is shown here: m = y₂ - y₁ / x₂ - x₁.
Since our slope or <em>m</em> equals -5, we start
by plugging a -5 in for <em>m</em> in our formula.
Now, y₂ - y₁ would be -5 - n and x₂ - x₁ would be 4 - 3.
So we have -5 = -5 - n/4 - 3.
First we would simplify 4 - 3 to get 1.
So in our next step we have -5 = -5 - n/1.
Now get rid of the fraction by multiplying both sides by 1
and since multiplying anything by 1 is itself, just cancel the 1.
So we have -5 = -5 - n.
Add 5 to both sides to get 0 = -n.
Divide both sides by -1 to get 0 = n.
So the value of n is 0.
