I have a few problems I need you to take a look at and tell me if I arrived at the right answer.
1. I am to use the intercepts to graph the equation x+3y=6
I used the formula y=mx+b using 3 and -6 for x I got these as my ordered pairs to graph (3, 1), (-6, 4)…Is this correct? I also got these two ordered pairs (0, 2) (3, 1)
2. Multiply -2/1*(-6/1): I got 12
3. Solve 3+4x<27 I got <6
4. Solve the compound inequality: 6>-4x+5 or 9 <(or equal to)-4x+2
My answer was (-oo,-7/4]u(-1/4,oo)
5. Is (5,2) a solution to 4x-2y=-6 I said no
6. Decide if the line is parallel, perpendicular or neither
5x+4y=2
4x-5y=4 I said neither
7. Solve using elimination: 5r-3s=11
3r+5s=61 I got (7, 8)
8. Graph using slope and y intercept: y=4/3x+3 I graphed (0, 3) and (3, 7)
9. Solve using elimination
2x+3y=1
4x+6y=2
I got 0…there is no solution

    I need to find the intercepts and then use them to graph the equation. 4y - 12 = 4x I started out 4y - 12 + 12 = 4x +12 getting 4y = 16x but I do not think I am on the right path..something does not look right..please guide :)
