List the coordinates for the points where the line
y=-1/2x-3 crosses the y-axis (separated by a comma)
y = -1/2 x - 3
The point where the line crosses the y-axis is the point where x = 0 .
So, plug in 0 for x and solve for y .
y = -1/2 (0) - 3
And -1/2 * 0 = 0 .
y = 0 - 3
y = -3
When x = 0 , y = -3 . That gives us the point (0, -3) .
