Slope is -2. y-intercept is 4.

Subtract 2x on both sides.

$y = - 2 x + 4$ $y=-2x+4$

Slope is -2. y-intercept is 4.

Start from $x = 0, y$ $x=0", "y$ is 4 at that point. When $x = 1, y = 2$ $x=1", "y=2$ . When $x = 2, y = 0$ $x=2", "y=0$ .

Similarly, when $x = - 1, y = 6$ $x=-1", " y=6$ . When $x = - 2, y = 8$ $x=-2", " y=8$ .
