You will now use graphical analysis to calculate the slope of the line. choose analyze from the menu. select automatic curve fit. select the proper stock function from the list. (hint: your answers from question 1 should you make the proper selection.) just below the graph you will see the slope value. remember that the symbol for slope is "m." when you choose ok to get back to the regular graph screen, you will see a little box on the graph. this box also shows the slope value. (remember that slope is "m.")

if you are unable to use graphical analysis, you can also graph your data on paper to determine the slope. hint: to determine the slope, use the formula m = (y2 - y1) ÷ (x2 - x1).

what is the numerical value of the slope of the line? show your work.

The slope can read from the graph after select Analyze / Linear Fit menu

or use Straight-line equations  formula

Graphical Analysis is graphing programs with  linear regression

General steps on the menu:

Make graph A on the vertical axis and B

on the horizontal axis.

If the data is OK and the graphed is what you want then

you find linear regression, if the  data is a straight line.

straight line will appear on your graph, with an equation for that line in a box. You can  read the slope and intercept directly from the  equation,

Or you can use Straight-line equations

General formula

or

y = mx + c

Where

m = straight-line gradient which is the slope of the line

x1, y1 = the Cartesian coordinate that is crossed by the line

c = constant

The formula for a gradient (m) between 2 points in a line

m = Δy / Δx

two different functions, f(x) and g(x)

F (x) = x2 + 1 g (x) = 5 - x

htps:

the inverse of the function f (x) = 2x-10

domain of the function
