A line is drawn through the points (-2,6) and (-4,-2). What is the y-coordinate of the point where this line intersects the y-axis? 

 

PLEASE HELP!!!!!!!!

slope = y1-y2   /   x1-x2

    = 6- -2  /   -2-  -4

    =8 / 2  =4

 

y=mx+b form

 

y = 4x + b      Sub in one of the points to find b

6 = 4(-2) + b

b = 14

 

y = 4x+14      when x = 0     b is the y intercept = 14
