Question

does (0,0) satisfy 3x-4y<12?
3(0)-4(0)<12

Answer 1

well what do you get as an answer when you plug 0,0 in to the equation

Answer 2

0<12.
zero is less than 12,so yes?

Answer 3

Remember when you see a point like this: (0, 0), this is called a coordinate and the first number is the x-value, the second being the y-value of the coordinate.

Answer 4

So with the coordinate (1, 3) for example, the 1 is your x-value, and the 3 is your y-value. This means that if you plug in a 1 for x and a 3 for y, you can solve the inequality or equation.

Answer 5

As you yourself have pointed out,

does (0,0) satisfy 3x-4y<12?
3(0)-4(0)<12

Therefore, 0 - 0 < 12 results when you substitute x=0 and y = 0. Is this last inequality true or false?

Answer 6

so it does satisfy the equation?

Answer 7

is that a question or a statement?:)
