Question

Choose the system of equations which matches the following graph.
2x + 2y = 8
4x + 4y = 16

2x – 2y = 8
4x + 4y = 16

2x + 2y = 8
4x – 4y = 16

2x – 2y = 8
4x – 4y = 16

Answer 1

You can find the equation of that line y=mx+b

if you can find the slope n,
and the y-intercept b

Answer 2

How would i start the equation?? what numbers would i plug in

Answer 3

the y-intercept is the y-value, where the line crosses the y-axis

Answer 4

so it would have to have a + and a - right?

Answer 5

the y is -4
