Identify the y intercepts for each equation & explain what it means: {3x-2y=-10 6x+y=0}

Question

help please 

Answer 1

The y-intercept is the point where the graph crosses the y-axis.  To find the y-intercept you set x = 0 and solve for y.

 

So in 3x-2y=-10, 3(0) - 2y = -10

-2y = -10 divide both sides by -2 and get y=5

 The y-intercept for 3x-2y=-10 is (0, 5).  The graph of the line will cross the y-axis at (0, 5).

 

6x+y=0, 6(0)+y=0

y=0

The y-intercept for 6x+y=0 is (0, 0). The graph of the line will cross the y-axis at (0, 0).
