Answer:

20z−8=4(5z-2)

Step-by-step explanation:

20z−8

20z can be written as 5 times 2 times 2 times z

8 can be written as 2 times 2 times 2

20z-8= 5 \cdot 2 \cdot 2 \cdot z- 2 \cdot 2 \cdot 2

Greatest common factor for 20z  and 8 is 2 times 2 = 4

Now take out 4 in common

20z−8=4(5z-2)

Find the slope of the line on the graph. Write your answer as a fraction or a whole number, not mixed number or decimal.
Vesna [10]

Answer:

<em>The slope is:</em>

m=-\frac{3}{2}

Step-by-step explanation:

The slope m of a line is calculated using the following formula

m=\frac{y_2-y_1}{x_2-x_1}

Where the points (x_1, y_1) and (x_2, y_2)  are two points belonging to the straight line

Notice in the graph that the line passes through the points

(0, 2) and (2, -1)

Then the slope is:

m=\frac{-1-2}{2-0}

m=\frac{-3}{2}
