Question

How do you graph `2x+y=4`?

Answer 1

Slope is -2. y-intercept is 4.

Explanation:

Subtract 2x on both sides.

`y=-2x+4`

Slope is -2. y-intercept is 4.

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

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

graph{y=-2x+4 [-18.17, 17.87, -6.34, 11.68]}
