Answer:
3
Step-by-step explanation:
us the formula
y1 - y2 divided by x1 - x2
=gradient

Step-by-step explanation:
Distance between (4, 3) and (8, 9):
(nearest tenth)
By "slope" I assume you mean slope of the tangent line to the parabola.
For any given value of <em>x</em>, the slope of the tangent to the parabola is equal to the derivative of <em>y</em> :
The slope at <em>x</em> = 1 is 5:
The slope at <em>x</em> = -1 is -11:
We can already solve for <em>a</em> and <em>b</em> :
Finally, the parabola passes through the point (2, 18); that is, the quadratic takes on a value of 18 when <em>x</em> = 2:
So the parabola has equation
