To find the average rate of change, use the following formula:

a and b represent the values of the interval:

Simplify the original equation by combining like terms:


Plug the interval values into the f(x) equation:


Plug in these values into the average rate of change formula:

The average rate of change over this interval is
-11.
An equation in the slope-intercept form y = mx + b the variable b is the y-intercept.
Or, if you replace the variable x with 0, you will also get the y-intercept.
y = 4(0) - 9
y = -9
So, the y-intercept is -9.
Answer:
12/5
Step-by-step explanation:
tan(G) = opposite side ÷ adjacent side
⇒ tan(G) = 24/10 = 12/5
X is 6 and y is -3 I’ll explain the solution right now
