Consider the line L given by the point-slope equation y+7= 1/2(x−18). The y-intercept of the line is located at (0, b)

What is the value of b?

b = -16

Step-by-step explanation:

To find the -intercept, rewrite the equation in the form (where is the slope and is the -intercept).

multiply out the brackets:  

Subtract 7 from each side:  

Therefore, when x = 0,  y = -16

So the value of b is -16

what is the answer?
