Allow me a few minutes to read the problem properly and then we'll start.

Step 1

Calculate the slope of the line

we ahve the points

L(-3,-3) and N(4,1)

m=(1+3)/(4+3)

m=4/7

the slope is positive

so

that means

the slope points up and right

answer is option third

step 2

Determine the run for triangle CDE

we have that

slope=rise/run

we have

slope=4/7

rise=DE=5+7=12

so

4/7=12/run

run=7*12/4

run=21 units -----> is ok

Please, Do you understand all the steps so far?

If you don’t need further explanation on this question, we can end the session. A pleasure to attend you, Remember that after our session, the answer is saved in your profile. Thanks and have a great day! Good Bye
