Question 448782
I presume the equation ius x+2y =4

write in the form y = mx +b

x+2y=4
-x on both sides
x-x+2y= 4-x
2y=4-x
/2
y=2-1/2 * x

y = -1/2 x +2
compare with y= mx+b. where m is the slope and b= y intercept.

m= -1/2 theslope. y intercept = b = 2

y==-1/2 x +2
when x=0, y=2 . ( 0,2)
when y=0 x=4 . (4,0)

Plot the points draw the line . you are done
