Aline is defined by the equation 2x + y = 4. which shows the graph of this line?

We have that
2x + y = 4

to graph this equation we will look for the x and y intercepts

step 1
find the x intercepts
y=0
2x+0=4-----> x=4/2-----> x=2
the point is (2,0)

step 2
find the y intercepts
x=0
0+y=4-----> y=4
the point is (0,4)

step 3
with the two points graph the line

see the attached figure

The answer would be: b
