Graph the equations to solve the system y= 1/2x + 6 y = -1/2x + 4

y=5, x=-2

Step-by-step explanation:

From the graph (attached), we can see that y=5, x=-2.

We can also solve system through algebra. (the easier and faster way)

y=1/2x+6

y=-1/2x+4

Substitute y with the first equation.

1/2x+6=-1/2x+4

1/2x+1/2x=4-6

x=-2

Then, substitute x with -2 in the equation.

y=1/2(-2)+6

y=-1+6

y=5

Agc and bgd are vertical angles

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
