Question

I need help with a problem I'm unsure about.
It's 3x + 4y = 8

Solving for Y
3 * 0 + 4y = 8
4y = 8
y= 2 (0,2)

Solving for X
3x + 4 * 0 = 8
3x = 8
x = 8/3

How do I graph this? It's the fraction that confuses me

Answer 1

Well, it's all about knowing where 8/3 is. 8/3 is just 2 + 2/3
So it's about a third of the way before you reach 3 :)

Answer 2

-3/4 is your slope -3/+4 down 3 units and right 4 units
or
+3/-4 is your slope up 3 units and left 4 units
either way your line is going down because of the negative slope

Answer 3

is (-4,7) the intersect when solving for x + 2y = 10, and 3x + 4y = 8?
