Aset of data points has a line of best fit of y=2.5x-1.5
what is the residual for the point (4,7)

Residual= -1.5

Step-by-step explanation:

Given : Equation of line y=2.5x-1.5

To find : the residual for the point (4,7)

By definition of a residual is generally a quantity left over at the end of a process.

Now firstly we find the value of f at x=4

f(x) =  2.5x  -1.5

f(4) =  2.5(4)  -1.5

f(4) = 10 - 1.5

f(4) = 8.5

The residual for the point (4,7) At x=4 f(x)=7

At x=4 f(x)= 8.5

residual= 7-8.5 = -1.5

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.
