Answer
$m=-\frac{3}{4}$
Work Step by Step
To find slope, we use the slope formula: $m=\frac{y_2-y_1}{x_2-x_1}$
We plug in the values for $x$ and $y$: $m=\frac{0-3}{4-0}$
We simplify the expression using the order of operations:
First, we simplify above and below the fraction bar by subtracting: $m=\frac{-3}{4}$
Then, we move the negative sign out front: $m=-\frac{3}{4}$
