Find the slope .

The slope for this problem is -4/3.

Step-by-step explanation:

To find the slope, we can look at it as Rise/Run. The rise is how many units up (+) a point is or how many units down (-) a point is from the starting point. The rise is how many units to the left or right a point is from the starting point.

Now that we understand Rise/Run, we can find the slope. If we go from the highest point, or the point farthest to the left in the picture shown, we can see that we need to go four units down to get to the same level as the next point, so we would be moving -4 units away from the point. We can also see the second point is 3 units to left.

With this information, we can now figure out that the slope is -4/3.

Don't hesitate to ask any questions.

m =rise/ran=y2-y1/x2-x1

m=slope

(x1, y1)=coordinates of first point in the line

(x2, y2)=coordinates of second point in the line

Step-by-step explanation:

find points.

then use formula & solve.

i think it is c, not positive though

step-by-step explanation:

just sum

10 + 10 = 20
