Answer:
The average rate of change cover the given interval is -6
Step-by-step explanation:
The average rate of change of a function over a range can be calculated by;
f(b) - f(a)/b-a
f(b) and f(a) refers to the respective y values of the x values a and b
Since we have a and b, we can get f(a) and f(b) from the plot
From the graph, since a = 0, f(a) is the y-intercept = 6
b = 1
f(b) = 0
So we have the slope as
= (0-6)/(1-0) = -6/1 = -6

Step-by-step explanation:
Answer:
2/3
Step-by-step explanation:
when multyplying a fraction and a whole number, its better if you put the whole number over 1 to make it a fraction, now you can multiply fractions easier, just multipl accross, 2*3 is 6, 9*1 is 9, now you have a fraction of 6/9 which can be simplified to 2/3
