The slope of this line of best fit is given in the following

Step-by-step explanation:

The line's slope equals the difference between points' y-coordinates divided by the difference between their x-coordinates. Select any two points on the line of best fit. These points may or may not be actual scatter points on the graph. Subtract the first point's y-coordinate from the second point's y-coordinate.A line of best fit (or "trend" line) is a straight line that best represents the data on a scatter plot. This line may pass through some of the points, none of the points, or all of the points.A line of best fit is a straight line that is the best approximation of the given set of data. It is used to study the nature of the relation between two variables. (We're only considering the two-dimensional case, here.) A line of best fit can be roughly determined using an eyeball method by drawing a straight line on a scatter plot so that the number of points above the line and below the line is about equal (and the line passes through as many points as possible).

Calculation the line of best fit

STAT → CALC #4 LinReg(ax+b) Include the parameters L₁, L₂, Y₁ (Y₁comes from VARS → YVARS, #Function, Y₁)

A more accurate way of finding the line of best fit is the least square method .

You now have the values of a and b needed to write the equation of the line of best fit. See values at the right.

Answer from: Quest

step-by-step explanation:

Answer from: Quest

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

(x^4) ^ ¼ = 81 ^ ¼

81 = 3^4 so (3 ^ 4) ^ ¼ = 3 ^ 1 = 3

by hand: (3 ^ 4) ^ ¼ = 3 ^ (4 x ¼) = 3 ^ 1 = 3 (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.
