Question

Tanika drew a line of best fit on a scatter plot as shown below​

Answer 1

C. she forgot the minus sign for the first term on the right side of the equation.

Explanation:

Tanika's work: 1.02(0.5)+7.09 = y

y = 7.6

She's missing the negative sign before 1.02. Her equation should have been -1.02(0.5)+7.09 = y

y = 6.58
