What subject is this if this is math I am good at it
Answer:
Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.
Point Form:
(1,1,0)Equation Form:x =1 ,y =1 ,z =0
Step-by-step explanation:
40 is the answer for the equation 20+20=40
Answer:

To find this you must find the slope first:

which is, after performing some calculating is -2.
Next you need to set up your eqaution:

when you set it up, and substitute the variables for your slope and points you should get this:


add 2 to both sides

subtract y from both sides
