Question

isosceles triangle lmn is graphed with vertices l(0, 1), m(3, 5), and n(6,1). what is the slope of side ln?
-\frac{4}{3}
0
\frac{4}{3}
3

Explanation:

Step1: Recall slope formula

The slope formula between two points $(x_1,y_1)$ and $(x_2,y_2)$ is $m=\frac{y_2 - y_1}{x_2 - x_1}$.

Step2: Identify points

For side $LN$, $L(0,1)$ is $(x_1,y_1)$ and $N(6,1)$ is $(x_2,y_2)$.

Step3: Substitute values

Substitute $x_1 = 0,y_1=1,x_2 = 6,y_2 = 1$ into the slope formula: $m=\frac{1 - 1}{6 - 0}=\frac{0}{6}=0$.

Answer:
