Nikolay [14]3 years ago
7 0

Answer:

y = - 0.5x - 1

Step-by-step explanation:

The equation is of the form

y = mx + c ( m is the slope and c the y- intercept )

m = - 0.5 is already given as y = - 0.5x

Using the ordered pair (0, - 1 ) ⇒ c = - 1

Thus

y = - 0.5x - 1 ← is the equation

What is the average rate of change for the line shown in the graph
kompoz [17]

Answer:

The average rate of change is 10.

Step-by-step explanation:

Since the average rate of change is the slope of a line, you'd solve this problem by finding the slope.

First, you can start by using the \frac{y_2-y_1}{x_2-x_1} method.

Plug in the points (0,10) and (1,20).

\frac{20-10}{1-0} =\frac{10}{1} =10

Therefore your answer is 10.

Hope this helped!

Factor completely. a^2 + 28a + 27
Tpy6a [65]
For factorisation it is necessary that you multiply the last and first values
Here we can see : we require 27a^2
SO if we multiply the answer should be 27 and if we add the answer should be 28 ....here goes !!

a^2 + 28a + 27

a^2 + 27a + 1a + 27

Here we can see : I we multiply 27 and 1 the answer will be 27a^2 but if we add 27 and 1 as shown then answer will be 28a:

a ( a + 27 ) + 1 ( a + 27 )

( a + 1 ) × (a + 27 )

HOPE IT HELPED!!
