True us the answer too your question.
Start with the point-slope form:
.
Then you substitue in the slope and coordinates from the point:

You don't do a lot of clean up to the form, with the exception of turning "minus negative 7" into "plus 7".

Thar be yer answer!
Answer:
Step-by-step explanation:
If you are saying that the hypotenuse is 10 cm the you have to solve the following equation using the Pythagorean theory.
4^2 + b^2 = 10^2
16 + b^2 = 100
16 - 16 + b^2 = 100 - 16
b^2 = 84
Find 
Answer:
4y^2-12y
Step-by-step explanation:
y^2+4y-16y+3y^2
=y^2+3y^2+4y-16y
=4y^2+4y-16y
=4y^2-12y
