campbell_st · Answer

can you use any method... or is there a specific method

anonymous · Answer

these are the choices they gave me 
	(–1, 2)
	(–9, 7)
	(0, 1)
	(1, 7)

campbell_st · Answer

ok... so a easy choice is graphically... so graph the lines and find the point of intersection use this site to graph them https://www.desmos.com/calculator

anonymous · Answer

Can you help me with graphing

campbell_st · Answer

just type the equation as its written it will graph it for you

anonymous · Answer

okay what do I do after that?

campbell_st · Answer

just look at the graph and find the point where the lines intersect

Did you go to the link that @campbell_st gave you, and typed in the equations?

anonymous · Answer

Yeah but I just don't know what am I supposed to do after that

kropot72 · Answer

Did you get this?

kropot72 · Answer

What is the x-value where the red and the blue lines intersect?
What is the y-value where the red and the blue lines intersect?
These values give the solution.

anonymous · Answer

it says -1, 2 & 0, 1.4

kropot72 · Answer

You need to look at only one of the dots, that is the dot where the red and the blue lines intersect. You have correctly identified this point as (-1, 2) which is the solution to the system of equations. The other ordered pair (0, 1.4) is the y-intercept and is not a solution.
