y = 3.
y = mx + b
m = 0
so y = 3.

If the slope = 0, the line if flat, parallet to the x-axis. So if it passes through some point at y, it passes through all points where y is that.
You could solve the normal way:
y = mx + b
3 = 0 * 4 + b
3 = 0 + b
3 = b
Plugging that back in we get y = 0x + 3 or y = 3.
But you should be able to see that when the slope is 0 and one point has y at 3, then y = 3 for all points.

m = 0 indicates a line parallel to x -axis. And it is passing through 4,3
So, y = 3 is the equation of the line. It passes through all values of x including 4 and its slope is 0.

It's got a zero slope so it's a horizantal line meaning that the slope would be just Y=3

EQT : y - y1 = m ( x - x1)
............y-3 = 0( x - 4)
............y - 3 = 0
