A quadratic regression is the process of finding the equation of the parabola that best fits a set of data. As a result, we get an equation of the form: y = a x 2 + b x + c where a ≠ 0 . The best way to find this equation manually is by using the least squares method.

To find the line, you need to use the point-slope formula because you're given both the slope and a point.
y - y₁ = m(x - x₁)
m = -2/5
x₁ = 10
y₁ = 3
y - 3 = -2/5(x - 10)
y - 3 = -2/5x + 4
y = -2/5x + 1
y = -2/5x + 1 is the line.
The rule when an exponent is raised by another exponent is:
(a^b)^c = a^(b*c)
In this case:
(4^3)^5
4^(3*5)
4^15
