x+2y=8
-x -x
2y=-x+8
divide by 2
y=-1/2x+4
using y=mx+b (m bing slope and b being the y intercept)
your graph should have a slanted line pointing towards the upper left corner and cross the y axis at 4 (0,4). it should also go through the points (2,3) (4,2) (6,1)
good luck

you ought to rewrite the equations like this : y = ( x - 8 ) / 2 and y = -a million - x and then you graph them , so actual purely take some values of x and also you acquire the values of y as an get mutually : you pick x = 0 , 2 , 4 , 8 and also you acquire y = -4 , - 3 , -2 , 0 and then you graph those factors reliable luck

y=4-x/2

x + 2 y = 8
2 y = 8
y = 4
just cover up the x and you'll get 2 y = 8, then you divide both sides by 2, so the answer is 4.

x + 2y = 8
2y = 8-x
y = 4 - 0.5x.
So you have y-intercept 4, gradient -0.5.
