The equation of the line of best fit using the slope-intercept formula y=mx+b is y = x - 5
<h3>Equation of the line of best fit</h3>
A line is the shortest distance between two points. The equation in point-slope form is expressed as:
y =. mx + b
m is the slope
b is the y intercept
Using the coordinate points (25, 20) and (60, 55)
Slope = 55-20/60-25
Slope = 35/35
Slope = 1
For the intercept
20 = 1(25) + b
b = 20 - 25
b = -5
Substitute
y = x + (-5)
y = x - 5
Hence the equation of the line of best fit using the slope-intercept formula y=mx+b is y = x - 5

Answer:
r = 22.5
Step-by-step explanation:
R = D/2 = 45/ 2 = 22.5
He needs to buy 3.6 spools but I guess that wouldn't be possible in real life so he needs to get 4 and then has some leftover.
12 3/5 / 3 1/2 = 3.6
The first one is 2x+y=-1
the second one is 13x+2y-1=0
