To find the slope of the line of the graph, pick any 2 points on the line as your coordinate pairs.
Thus, on the line, let's pick 2 points as our coordinate pairs at:
When x = -6, y = 5 => (-6, 5), and
When x = 3, y = -1 => (3, -1)
Let (-6, 5) be (x1, y1), and (3, -1) be (x2, y2)
Answer:
144
Step-by-step explanation:
The equation to find c is:
So put -24 into b:
Which simplifies to:
144
So if you want to test this:
x^2 - 24x + 144
is
(x-12)^2
