Question

4 pointsTriangle BAC is shown on the coordinate grid. The coordinates of eachvertex of the triangle are integers. Numerical answers as decimal or wholenumber only (do not write as a fraction).6AB5321с012What is the slope of BC?Your answerThis is a required question

Answer 1

The Solution.

The slope of line BC is given below:

`\begin{gathered} \text{slope = }(y_2-y_1)/(x_2-x_1) \\ B(1,6)\rightarrow(x_1=1,y_1=6) \\ C(4,0)\rightarrow(x_2=4,y_2=0) \end{gathered}`

Substituting the values above into the formula, we get

`\text{Slope = }(0-6)/(4-1)=-(6)/(3)=-2`

Thus, the correct answer is -2.
