Dimas [21]3 years ago

It would be 1n - 12 + 8y.
4n - 3n = 1n
12 + 8y don’t mix so we can leave it.
Therefore: 1n - 12 + 8y

Find the slope of the line passing through the points using the slope formula
r-ruslan [8.4K]

The slope formula is m= y2-y1/x2-x1.

m= 4-0/2-5

m=4/-3

Therefore, 4/-3 is the slope.

What is the slope of the line on the graph? Enter your answer in the box. A coordinate grid that includes the line y equals nega
RUDIKE [14]

we have

the equation of the line is y=-2x

the points are

A(3,-6)\\B(0,0) \\C(-3,6)

<u>Method 1</u>

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form y/x=k or y=kx

In this problem we have a direct variation

The constant of proportionality k is equal to the slope of the line

k=-2

so

m=-2

therefore

<u>the answer is</u>

the slope of the line is equal to

m=-2

<u>Method 2</u>

we know that

the formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have

A(3,-6)\\B(0,0)

substitute in the formula

m=\frac{0+6}{0-3}

m=\frac{6}{-3}

m=-2

therefore

<u>the answer is</u>

the slope of the line is equal to

m=-2
