The equation y=ax describes the graph of a line. if the value is negative the line is what?

If the value of a is negative the line is decreasing.

Step-by-step explanation:

The value of a, the coefficient of x, is the slope.

If the slope is positive, the line is increasing from left to right.

If the slope is negative, the line is decreasing from left to right.

If the slope is negative, then the line goes downwards when reading from left to right.

The general linear equation is given by:

y = a*x + b

Where a is the slope and b is the y-intercept.

In this case, our equation is:

y = a*x

So this is a linear equation where the y-intercept is just 0.

The value of a defines the slope of the line, in the case where the slope is negative, the line is a decreasing line, so it goes downwards if we read it from left to right.
