3(x-5)=1+(5x+2x)
3x-15=1+7x
-15=1+7x-3x
-15=1+4x
-15-1=1+4x-1
-16=4x
-16/4=4x/4
-4=x
Answer:
6/5
Step-by-step explanation:
We can find the slope given two points by
m = (y2-y1)/(x2-x1)
= (1 - -5)/(7-2)
= (1+5)/(7-2)
=6/5

Answer:
Extrapolation
Step-by-step explanation:
Given
Explanatory variable
Response variable
Required
Predicting y outside range of x is called
This is referred to as extrapolation.
Take for instance, the range of x is: 1 - 9
You have extrapolated when, 10 is assumed to be the value of x and this value is entered in an equation to predict y.
