<u>Answer</u>
Part 1: l = -1.665g
Part 2: Max-mum the spring can support.
Part 3: The spring constant.
<u>Explanation</u>
Gradient is also called the slope.
Slope = (change in y) /(change in x)
= (60 -40)/(6.7 - 40)
= 20 / -33.3
= - 0.600600601
Since the graph is a straight line, the equation would be,
m ∝ l
m = kl Where K is the constant.
<u>g</u> = -0.60l
l = -1.665g
<u>Part 2</u>
The Y-intercept represent the mix-mum weight the spring can support.
<u>part 3</u>
The slope in this case represent the spring constant.
your answer is going to be x 22 and y 34

Answer: f(x) = (1/3)x + 3</h3>
This is basically in the form y = mx+b with m = 1/3 as the slope and b = 3 as the y intercept. I'm using f(x) in place of y to indicate function notation.
==========================================
Work Shown:
The goal is to solve for y.
x - 3y = -9
-3y = -9-x ... subtracting x from both sides
-3y = -x-9
y = (-x-9)/(-3) .... dividing both sides by -3
y = -x/(-3) - 9/(-3) ... break up the fraction
y = (1/3)x + 3 .... simplify
f(x) = (1/3)x + 3 .... replace y with f(x)
The explanatory variable is synonymous for the input or the independent variable, this word is used in a different context, usually statistics. A way to think of it is that the explanatory variable EXPLAINS how and why the dependent variables are.
