Answer 2

Answer:

yes, b = 8

Step-by-step explanation: no. are 1, 1, 1

First number is 1

The second number is 2 - 1 which is equals to 1

The third number is given as b - 3 - 4 which is equals to b minus 7

as it is given that the points are collinear so the slope of all the points is going to be the same that 4 b minus 7 is equals to 1 and hence the value of b is 8
