What is the slope?

Luda [366]

Answer:

-3

Step-by-step explanation:

Find two easy to read points on the graph.

I see (0, 1) and (-1, 4).

slope = rise/run

Start at (0, 1). Go up 3 units. That is a rise of 3. Now go left 1 unit. That is a run of -1.

slope = rise/run = 3/(-1) = -3

Answer:

$\frac{1}{7}-3(\frac{3}{7}n-\frac{2}{7})=1-\frac{9}{7}n$

Step-by-step explanation:

Given : Expression $\frac{1}{7}-3(\frac{3}{7}n-\frac{2}{7})$

To find : Combine like terms to create an equivalent expression ?

Solution :

Step 1 - Write the expression,

$\frac{1}{7}-3(\frac{3}{7}n-\frac{2}{7})$

Step 2 - Apply distributive property, $a(b+c)=ab+ac$

$=\frac{1}{7}-3\times \frac{3}{7}n+3\times \frac{2}{7}$

$=\frac{1}{7}-\frac{9}{7}n+\frac{6}{7}$

Step 3 - Combine like terms,

$=\frac{1}{7}+\frac{6}{7}-\frac{9}{7}n$

$=\frac{1+6}{7}-\frac{9}{7}n$

$=\frac{7}{7}-\frac{9}{7}n$

$=1-\frac{9}{7}n$

Therefore, $\frac{1}{7}-3(\frac{3}{7}n-\frac{2}{7})=1-\frac{9}{7}n$

Step-by-step explanation:

9x - 5 = 7x + 25 ......(vertical angle and corresponding angle )

9x - 7x = 25 + 5

2x = 30

x = 30 / 2

x = 15
