Respuesta :

The complete question is

"A data set consists of the following data points: (2,4),(4,7), (5, 12)

The line of best fit has the equation y = 2.5x - 1.5. What does this equation predict for a value of x = 7?

O A. 16

O B. 19

O C. 20.5

O D. 175

0 0 0

a. no. both a and b are incorrect.

b. no. the value for b is incorrect.

c. no. the value for a is incorrect.

d. yes. this is the correct equation."

The  equation predict for a value of x = 7 in equation  y = 2.5x – 1.5  is  (x, y) = (3, 16). Option B is correct.

What is a system of equations?

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

"A data set consists of the following data points: (2,4),(4,7), (5, 12)

y = 2.5x - 1.5

Puy x = 7

y = 2.5(7) - 1.5

y = 17.5 - 1.5

y = 16

The  equation predict for a value of x = 7 in equation  y = 2.5x – 1.5  is  (x, y) = (3, 16). Option B is correct.
