On a coordinate graph with y on the vertical axis and x on the horizontal axis,consider the line which is the graph of the function Y = 60 - 4X.The slope of this line is
A)4.
B)60.
C)-2.5.
D)-4.0.
E)-40.

The slope of a line can be found using the formula:

slope = (change in y) / (change in x)

In this case, the equation of the line is Y = 60 - 4X. We can rewrite this in slope-intercept form:

Y = -4X + 60

Now we can see that the slope is -4. Alternatively, we can also see that the coefficient of X in the equation is -4, which is the same as the slope. Therefore, the answer is D.
