X+y=8 x-y=2 graphical method
X+y=8 x-y=2 graphical method-The graph of a circle hgas the form (xa)^2 (yb)^2 = R^2 R the radius and (a,b) the coordinates of the centre but your graph equation has a () ( (x4)^2 () (y8)^2 ), so it isnt a graph of a circleLooking at we can see that the equation is in slopeintercept form where the slope is and the yintercept is Since this tells us that the yintercept is Remember the yintercept is the point where the graph intersects with the yaxis So we have one point Now since the slope is comprised of the "rise" over the "run" this means
