Question

Can someone explain this and help me?

Answer 1

Answer:  (2,-5)

Step-by-step explanation:

The slope of the line formed by this set of number is 2 (y increases by 2 for every 1 increase in x).  The line has the form y = 2x + b.  Enter one of the data points to find b.

y = 2x + b  for (2,3)

3 = 2*2 + b

b = -1

The equation is y = 2x - 1

The missing value:  y =2*(-2) - 1

                                 y = -5

(2,-5)
