Answer:
2
Step-by-step explanation:
To find the slope of the graphed line, you take two points. I have chosen (0, 4) and (8, 0)
The formula of a slope is (y value of second point
value of first point) divided by (x value of second point
value of first point):

The slope for a perpendicular line is 2.
Answer:
11/15
Step-by-step explanation:
22/30 = 11/15 because they both have a common factor of 2 in the numerator and denominator.

Answer:
B
Step-by-step explanation:
The exponential function has the form
where a is the starting value or y-intercept. B is the rate of change and x is the variable typically time. In this situation,
has starting value 4, rate 3 and a -x.
Normally an exponential curve glides left to right growing steeper as it goes. But a -x flips this behavior. The curve starts very steep then gradually slows down. This means only graphs B or D are options. Since only graph B of these two has a y-intercept at 4, graph B is the solution.
