What is the y-coordinate of the y-intercept of the line that passes through the point (2,-3) and has slope 1/2?

We  have  this  equation :

 

y = mx  +  b        where  b  is the y intercept   and  ( x, y)  is a point on the  graph....so we have

 

-3 = (1/2)(2)  + b

 

-3 = 1  +  b      subtract   1  from   both sides

 

-4  =   b
