Question

Solve graphically x+y=4

Answer 1

Answer:

Step-by-step explanation:

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]}
