5 Question 1 (a,b,c) are related to the graph above, and 2, 3, and 4 are different questions:

1a) Enter the letters of the points that lie on the line y= 1/2x+3 ( I found points I,E, F what else are there)

1b) Enter the letters of the points that are below the graph of y= -1/3x

1c) Enter the letters of the points that are on the graph of |x| = |y| .

2) What are the coordinates of the intersection of the graphs of 3x-y^2=12 and y=-3?

3) In which quadrant(s) do the graphs of y=x^2 and y=3x+10 intersect?

4) The graphs of these two equations intersect in how many points?

x^2+y^2=25

x^2-y^2=3

For 1a, the point B also lies on the line y = 1/2*x + 3.

Find the area of the region bounded by the y-axis,y=6 the line , y=1/2x and the line .

Could you do this?

For question 2) sub y=-3 into the first equation and solve for x

In fact they are all just fairly simple simultaneous equations

Please do not post big chunks of homework again.

One post = one question.

I am sorry.

I have seen people doing that in the past so I thought it would be okay. If you would like I could repost the questions one by one.

I did distribute and got this:

3x-(-3)^2=12

3x+9=12

3x=3

x=1

3(1)-y^2=12

3-y^2=12

-y^2=9

What do I do after??????

ok we are looking at Q2

2) What are the coordinates of the intersection of the graphs of 3x-y^2=12 and y=-3?

3x-  [(-3)^2]  =12

I have done a correction.  Make sure you understand it and take it from there.
