Question

Sketch the graph of the following equation on your own paper, then choose the correct graph below.
5x + y = 4

Answer 1

Two points determine a line.  You just draw the line through the points and keep on going.

 

This equation of the line is in Standard Format, so it pretty easy to find the y-intercept (the point where x=0) and the x-intercept (the point where y=0).

 

These are those points:

     (4/5, 0)

     (0, 4)

 

If you don't want to plot a fraction, look at the equation again.

When x=1, then y=-1.

     (1, -1)

 

     or (2, -6) could be used.
