A graphing calculator finds the regression line to be
y = 5.5x + 52
Plug in 3 into the equation.
y= 5(3) +8
Combine like terms.
y= 15+ 8
y= 23
I hope this helped!
The x intercept of the line is at x = 10.
The x intercept is always the value of x when all other values are equal to 0. So in this case, we put 0 in for t and then solve.
-2x + 5t = -20
-2x + 5(0) = -20
-2x = -20
x = 10
Answer:
13 3/4

2 3/4 is 11/4 when converted into an improper fraction.
5 is 5/1 when converted into a fraction.
11*5 is 55 (numerators)
4*1 is 4 (denominators)
55/4 is 13 with 3/4 remaining
13 3/4
