x+y=4 solve it graphically

Answer 1

★ Question→

→ x+y=4 solve it graphically.

_________________________

★ Solution

Let's put this into slope-intercept form to make graphing easier. The general equation for that form is:

→y=mx+b

where m is the slope and b is the y-intercept. So we'll get:

→x+y=4

→y=−x+4

The y-intercept is 4, so that's a point →(0,4).

The slope is −1

, so the graph will move one point down for every point it moves right. The next point we can graph is (1,3)

. Use a straightedge to connect those two dots and make the graph. It'll look like this:

→graph{-x+4 [-10, 10, -5, 5]}
