The table below models the price of pizza based on the number of toppings. Calculate the linear regression equation (equation of least squares, line of best fit)
Number of toppings 0,1,2,3,4,5,6 price of pizza( in dollars)12,13.5,15,16.5,18,19.5,21 what is the the equation y=?

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
