Y = -2x + 4
6x + 3y = 6x + 3(-2x + 4) = 6x - 6x + 12 = 12
⇒ y = -2x + 4 == 6x + 3y = 12 ⇒ invinite solutions: 12
⇒ no solutions -12, -4, 0, 4
I think the answer is 3, -8/2 / 6/-3 .... then you flip and multiply to get to -8/2 x -3/6 which = 24/8 which is equal to 3
The intercept method of graphing is quick and easy.
Find the x-intercept by setting y = 0 and solving for x:
y+1=1/3(x−3) => 0<span>+1=1/3(x−3)
Multiply both sides by 3: 3 = x - 3. Then x = 6, and the x-int. is (6, 0).
Find the y-int by setting x = 0 and solving for y:
</span><span>y+1=1/3(0−3)
Mult both sides by 3: 3y+3 = -3, so that 3y = -6, and y = -2.
Then the y-intercept is (0,-2).
Plot these 2 points. Then draw a line thru them.</span>
Is one piece good? and how long is it?
