Question

Anyone know the answer? Also could you put down what equation I’m supposed to use?

Answer 1

The bottom two are your answers.

Explanation:

What you do is use the slope formula which is y_2-y_1/x_2-x_1.

So for PQ it will be 12(which is y_2)-6(which is y_1)/4(which is x_2)-5(which is x_1) which equals -6.

12-6/4-5=-6.
