3x + y = 2

4y = 12 - 12x

HOW DO YOU DO THIS?

**Henry**, Monday, January 30, 2012 at 9:46pmGraph each Eq; the point where they intersect is the solution. Then verify

your solution by solving them mathematically.

Eq1: 3x + y = 2.

(-2,8), (0,2), (2,-4).

Eq2: 12x + 4y = 12.

Divide both sides by 4:

3x + y = 3.

(-2,9), (0,3), (2,-3).

Use the points given or any convenient points.

NOTE: The 2 Eqs have equal slopes. Therefore, they do not intersect and

there are no solution. Be sure to do

the graphs anyway.

m1 = -A/B = -3/1 = -3.

m2 = -A/B = -3/1 = -3.
