Draw the graph of the linear equation whose solutions are represented by the points having the sum of the coordinates as 10 units.
x + y = 10
y = -x + 10
if x = 0 , y = 10
if y = 0 , x = 10
draw line through those two intercept points
y = -x + 10
if x = 0 , y = 10
if y = 0 , x = 10
draw line through those two intercept points
