Re: solving x + 2y = 6 for y, and then graphing

I know the y-intercept is 3, but when I try to graph even numbers, it gets confusing.

solving x + 2y = 6 for y, and then graphing

solving x + 2y = 6 for y, and then graphing

I tried to solve for y, and got y= -x/2 + 3. This is hard to graph.

Re: New Lessons?

You definitely need Geometry for all the lost 8th Graders out there.

Connections: 5X 1st of 3 consec. even integers is 14 more

This problem baffles me.

5 times the first of 3 consecutive even integers is 14 more than 3 times the second. What is the third consecutive integer?


The equation I have so far is 5x(first integer) = 3y(second integer) + 4.

Do I solve for X? Or do I solve for Y? Or something completely different?

Re: [SPLIT] length of a rectangle is 3 more than twice its width

1. W

2. 2w + 3

3. P = 2(w) + 2L

4. P = 2(w) + 2(2w + 3)

5. 2W + 4W + 3 = 48

6W + 3 = 48

48 - 3 = 45

6w = 45
/6 /6

w = 7.5

Re: [SPLIT] length of a rectangle is 3 more than twice its width

I tried again, and came up with 2w + 3 + 2w = 48

Solve for W = 11.25
