What is the x-intercept of the graph of y equals x2 - 4x plus 4?

The x-intercept will happen when y equals zero. So we can say:
x2 - 4x + 4 = 0
(x - 2)2 = 0
x - 2 = 0
x = 2
So the x-intercept happens at (2, 0). To verify, just plug 2 into the original equation:
y = 22 - 4(2) + 4
y = 4 - 8 + 4
y = 0

How do you graph the equation 8x plus 2y equals -1?
Same way you graph y = -4x - 0.5
What is the effect on the graph of the equation 4x plus 2y equals 12 is changed to 36?
I guess you mean 4x + 2y = 12 is changed to 4x + 2y = 36. The graph is translated (shifted) up the 7 axis by 24.
What is the graph of -4x plus 7y equals -28?
-4x=7y-28 -4x+28=7y -4x/7+4=y A line with a y-int of 4 and a slope of -4/7
-y equals 4x plus 1 4x plus y equals 2?
