Find the rate of change

Mathematics
1 answer:
eimsori [14]3 years ago
3 0

Answer:

9

Step-by-step explanation:

The rate of change of a function f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

here [ a, b ] = [ 3, 7 ]

f(b) = f(7) = 47 and f(a) = f(3) = 11, hence

rate of change = \frac{47-11}{7-3} = \frac{36}{4} = 9

What is the equation of (0,2) and (3,0)
ivolga24 [154]
Let's first find the slope. This is (y_2 - y_1)/(x_2 - x_1), where (x_1, y_1) and (x_2, y_2) are points.

For this problem, our slope is (0 - 2)/(3 - 0) = -2/3.

We can now use the point-slope formula to find the equation of our line:
(y - y_1) = m(x - x_1)
(y - 2) = -2/3(x - 0)
y - 2 = (-2/3)x
y = (-2/3)x + 2

The equation of our line is \boxed{y = -\frac{2}{3}x + 2}.
