find the simultaneous solution by graphing. (10 points)\nsupply is defined as the amount produced. demand is defined as the amount consumers will purchase. define the y axis as price, the x axis as quantity.\nit has been determined that demand is denoted by: x + y = 6\nit has been determined that supply is denoted by: x - y = 2\ngraph the solution and label the point of intersection as the equilibrium point.
Answer
Explanation:
Step1: Rewrite equations in slope - intercept form
For demand $x + y=6$, rewrite as $y=-x + 6$. Here the slope $m_1=-1$ and y - intercept $b_1 = 6$. For supply $x - y=2$, rewrite as $y=x - 2$. Here the slope $m_2 = 1$ and y - intercept $b_2=-2$.
Step2: Find intersection point algebraically
Set the two equations equal: $-x + 6=x - 2$. Add $x$ to both sides: $6 = 2x-2$. Add 2 to both sides: $8 = 2x$. Divide by 2: $x = 4$. Substitute $x = 4$ into $y=-x + 6$, we get $y=-4 + 6=2$.
Answer:
The equilibrium point (point of intersection) is $(4,2)$
