Question

Graph the second equation to find the solution of the system of equations.

y = –x,

y = 2x + 6

What is the point of intersection

Answer 1

Answer: (-2,2)

Explanation: I plugged it into a graphing calc!

Answer 2

Answer:

So the point of intersection would be -x=2x+6

and then we'll subtract 2x on both sides and get -3x=6

this will result in x=-2

Then we'll substitute that into y=-x, so y=2

Therefore the point of intersection is (-2,2)

Hope I helped, have a nice day :)
