Question

What is the slope of the line y = 3?

Answer 1

slope of line y=mx+c will be m.
and
y=3 can also be written as y = 0x+3

Answer 2

Think about what this graph looks like. No matter what value you select for x, the corresponding.

Value for y is 3.

If x = -5, then y = 3.

If x = 0, then y = 3.

If x = 8, then y = 3.

If you plot lots of points such as these, you will see that y is a horizontal line through
the point y = 3 on the y-axis.
.
Now think about the definition of slope.

Slope is the change in x divided into the corresponding.

Change in y.

Although x can change along this horizontal line, notice that y never changes.

So the change in y is zero.
.
Therefore, any change in x divided into the change in y is the same as the change in x
divided into zero.

The answer is zero.

Therefore, for y = 3 the slope is zero.

In fact, for any horizontal graph the slope is zero.

Answer 3

zero thats correct
