For the function f(x) = x²  6x + 8,
Find the yintercept, the equation of the axis of symmetry, and the xcoordinate of the vertex. a) what is the value of the ycoordinate for any xintercept? explain.
b) find the x intercept for the following line: y = 3x  6 Help graph... 6x + 5y= 30... my answer was 6/5x + 6, am I correct when graphing?
How do I graph it? Do I start at (0,6) than move 6 units down, 5 units to the right and plot, then what?
