how do i find the slope

Question

,A company has a manufacturing plant that is producing quality pairs of pants. They find that in order to produce 170 pairs of pants in a month, it will cost $4910. Also, to produce 310 pairs of pants in a month, it will cost $8130. Find an equation in the form y=mx+b,
y=mx+b,
where x
x
is the number of pairs of pants produced in a month and y
y
is the monthly cost to do so

Answer 1

These are your following points:

 

(170, 4910) and (310, 8130)

 

 

To find the slope between these two points, use the formula

 

m = (y₂ - y₁) / (x₂ - x₁)
