2=1/7(-1)+b
Solve for b

b= 15/7

Step-by-step explanation:

multiplying a positive and a negative equals a negative (+)x(-)=(-)

2= - 1/7 x 1 + b

any expression multiplied by 1 stays he same

2= - 1/7 + b

move variable to the left hand side and change the sign

- b +2= - 1/7

move constant to the right hand side and chane the sign

- b= -1/7 -2

calculate the difference

-b = -15/7

chnage the signs on both sides of the equation

b=15/7
