math help!!!

stuck!! pls help/explain!!!

2. Do the values in the table represent a linear function? If so, what is the function rule? (1 point)

x = -2, 0, 2, 4
y = -4, 0, 4, 8

The values do not show a linear function.
Yes, they show a linear function; y = x + 4.
Yes, they show a linear function; y = 2x + 2.
Yes, they show a linear function; y = 2x.

3. Write an equation for the line shown in the graph. (1 point)

the line is on a negative slope, bottom right, top left.
top left: 10
bottom right: it seems like it goes to 10, but it doesnt show.

10 = 4x
y = 2x + 10
y = 10x – 2
y = ­–x + 10

thanx!

  6. A linear function is a fun with points that lie on a line. You can write a linear function in the form f(x) = mx + b, or y = mx + b.

    Hope that helps! :D
