Rewrite your function as a equation:
y=0.15x -75
Use the slope-intercept form to find the slope and y-intercept:
y=mx+b
Find the values of m and b using the form y=mx+b
m=0.15
b= -75
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 0.15
Y-Intercept: -75
<span>c = w*45/13 + 60/13
I will be assuming that the equation will be linear since there are only 2 data points available. The form of the equation will be
c = aw + b
where
c = calories burned
a = some constant
w = weight
b = some other constant.
If you look at the equation, you'll notice that it looks like the equation for a line i slope intercept form. So first, let's calculate the slope of the desired equation.
a = (600-420)/(172-120) = 180/52 = 45/13 = 3.461538462
Now we have the equation
c = w*45/13 + b
Substitute the values for a known point, giving
420 = 120*45/13 + b
Now solve for b
420 = 120*45/13 + b
420 = 5400/13 + b
420 - 5400/13 = b
5460/13 - 5400/13 = b
60/13 = b
So now the equation is
c = w*45/13 + 60/13</span>

Answer:
B. 4( a + b + 2)
Step-by-step explanation:
Task: Simplify 2(2a + b) + 8
1. Distribute the 2
4a + 2b + 8
---------------------
Evidently, that is the same as A, so A is correct.
Now if we try C, 4a + 2(b+4), we see we need to simplify to check.
So let us distibute the 2.
4a + 2b + 8. Also correct.
This probably means that B is incorrect.
4(a + b + 2)
Let's distribute the 4.
4a + 4b + 8
This is incorrect because only have two "b".
