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.
<h3>What is a system of equations?</h3>
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.
