Answer: Slope = - 1000.
Explanation:
The line of best fit of the graph will be linear.
The general linear equation can be expressed as;
Y = MX + C
Where the Y variable represents the volume in the experiment as dependent variable and the X represent the pressure as independent variable.
The equation can be rewritten as:
V = MP + C
Where C is the intercept.
Given that
V = 200, 100, 50, 25, 12.5 and
Pressure P = 0.1000, 0.2000, 0.4000, 0.8000, 1.6000
The slope M can be calculated by using the formula
M = (V2 - V1)/ (P2 - P1)
Where V1 = 200, V2 = 100, P1 = 0.1, P2 = 0.2
Substitute all the parameters into the formula
M =( 100 - 200)/ ( 0.2 - 0.1 )
M = -100/0.1
Slope M = - 1000
