Question

Line n has no x-intercept and it’s y-intercept is (0,-4)

Answer 1

y = 4

Explanation:

Since the line has no x-intercept, this means that the line has a slope of 0, meaning it is a horizontal line. So with the equation y = mx + b, mx cancels out to 0 because there is no slope. This leaves y = b, where b = 4. So the answer is y =4

Answer 2

y = -4

Explanation:

If the line has no x-intercept, then it's a horizontal line with equation

`y=a,\ a\\eq0`

The line passes through the point (0, -4). Therefore the equation of this line is:

`y=-4`
