Question 180719
Find the y values for the 3 x values given. These are the points you want to plot.
{{{2x+y = 4}}}
{{{y = 4 - 2x}}}
when x = 0, y is 4    (0,4)
when x = 2, y is 4-4 = 0  (2,0)
when x = 4, y = 4-8 = -4 (4,-4)
Not plot those three points and draw the line that connects them
{{{graph(400,400, -10, 10, -10, 10, 4 - 2x)}}}
