-3

Step-by-step explanation:

1. Choose two coordinates on the line and count up and over to get the slope. For example, let's use coordinates (0,4) and (1,1).

Remember, slope is equal to rise/run. However, since the line is drawn in a downward diagonal direction, the slope is negative.

Start from (1,1) and count up and then left until you get to (0,4).

Count up 3 and left 1

Rise/run = -3/1.

2. Reduce it down to 3.

Slope is -3

the answer is c

hope this !

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
