Answer:
y = -2x + 2
Step-by-step explanation:
The equation of a line is y = mx + b.
First we want to find m, the slope. We can used the coordinates to do so:
Now we know that the equation is y = -2x + b. We can plug in the coordinate (3, -4) to find b.
So the equation is y = -2x + 2.
Answer:
The average rate of change between x = 2 and x = 4 is of 4.
Step-by-step explanation:
Average rate of change:
The average rate of change of a function f(x) in an interval [a,b] is given by:
In this question:
Thus:
Average rate of change:
The average rate of change between x = 2 and x = 4 is of 4.
