Write an equation of the line that passes through (0, 4) and (0, -3)

Step-by-step explanation:

So first of all we need the slope of the line we are trying to findWe get the slope by using the following formula So when you have two pairs of points, it will be and so our points are; (0,4) the first point, so and(0.-3) the second point, so Put this in our equation Oh no, that can't be right, any number divided by zero is undefined, meaning can't be answered. So this line has no slope So how do we know the equation? Remember, (a) if the line is horizontal, then the slope is 0,(b) if the line is vertical then the slope is undefinedSo our line is vertical, meaning it is an equation of xIf it were horizontal it would be an equation of ySo vertical, it is How do we know what x equals? Just look at our points (0,4) and (0,-3)For both of them and this is our equation!
