Adata 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 = 3?

C) 6

Step-by-step explanation:

We will substitute 3 in place of x:

y = 2.5(3) - 1.5

y = 7.5 - 1.5

y = 6

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
