Which function has a constant additive rate of change of -1/4?

The first graph has this property.

Step-by-step explanation:

The first graph, consisting of a straight line with decreasing slope, is the correct answer choice.  We can verify that the slope of this line is -1/4 by reading "rise" and "run" from the graph and writing the ratio rise / run.

The second graph is a quadratic whose slope varies as we move along the graph.

The third and fourth cases do show constant rates of change, but neither is -1/4.

y/x=18

step-by-step explanation:

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
