Determine the slope
Represent the given as x or y
Taking the weight as explanatory variable;
We have:
x = 2.1; y = 3.4
x = 7.5; y = 70
Slope is calculated as:




<em>Hence, the slope is 12.33</em>
It a measure of the amount of variation or despersion of a set of values
Answer:
Step-by-step explanation:
First, you distribute the 4 and 7 to the stuff inside the parentheses 28 - 12x = 28 - 14x then add 28 to both sides -12x = -14x then add 14x to both sides 2x = 0 then divide both sides by 2 x = 0
Answer:
y = 2/5x - 5
Step-by-step explanation:
y = 2/5x - 5
(If you go to desmos.com you can graph any equation. It really helps. I'm doing similar things in class, I use it all the time.)
Answer:
y = (-1/80)x^2 +2x
Step-by-step explanation:
The graph of the equation for the arch will go through the points ...
(0, 0), (160, 0), (80, 80)
We can start by making use of the zeros to write the function ...
y = a(x -0)(x -160)
To make the graph go through the point (80, 80), we must have ...
80 = a(80 -0)(80 -160) = (-80^2)a
-1/80 = a . . . . . . divide by the coefficient of "a"
So, our equation is ...
y = (-1/80)x(x -160)
y = (-1/80)x^2 +2x
