QUESTION
What is the y-intercept for the equation ## 7x + 2y = - 12##?
The y intercept is ##(0, -6)##
The y-intercept of a line is the value of y at the point where the line crosses the y axis. At this point ##x=0##
Substitute into the equation ##x=0## so you get:
##7(0) +2y = -12##
##0 + 2y = -12##
##2y = -12##
##y = -6##
The y intercept is ##(0, -6)##
