Answer:

30/13

Step-by-step explanation:

The rate of change of any linear function is the slope of the line, written as (change in y)/(change in x), more commonly remembered as rise over run.

If we are given two points, (x_{1}, y_{1}) and (x_{2}, y_{2}), the slope of the line between those points is (y_{2}-y_{1})/(x_{2}-x_{1}).

We can plug in any two points on the line. I will randomly pick (-1, -17) and (-7.5, -32). Plugging into the formula gives (-32-(-17))/(-7.5-(-1))=-15/-6.5=-30/-13=30/13.

This means the slope of the line and hence the rate of change is \boxed{30/13} and we're done.

Question 11
dem82 [27]

Answer:

There were 49 questions on this Geometry test.

Step-by-step explanation:

You can start by setting up a proportion:

x = total number of questions on Geometry test

\frac{37}{x} = \frac{75.51}{100}

Now, to solve for x, cross multiply:

75.51x = 3700

Finally, isolate x and solve:

x = 49.0001324328

This is very close to 49.
