Slope intercept form is y=mxb Really, it is more like "Rise/Run Slope of a line from the yintercept form" If you want to know the xintercept form you can solve the equation for x y=2x4 would become x=1/2y2 Now plug in zero for y and you will have what x is equal to (2) The reason we use y=mxb is because the idea of rise/run noSo your answer is (1,0) To solve by substitution, you would take one of the equations and put the second in where the variable is y=2x2 y=x1 The second equation is y= so wherever there is a y in the first equation, your going to put the second equation y=2x2 x 1 = 2x 2Problem 1 (15 points) Find the absolute maximum and minimum values of f(x;y) = exy on the domain 2x2 y2 1 Solution We rst check for critical points on the interior of the domain using the
