Answer:

$\frac{1}{8}$

Step-by-step explanation:

The formula for finding the slope of a line is;

$\frac{y_{2} - y_{1} }{x_{2} - x_{1}}$

Any two coordinate pairs ( (x,y) ) on the given table can be used, for this problem, let us use the first two given pairs.

( -8 , 2 )

( 0 , 3 )

$x_{1} = -8\\y_{1} = 2\\x_{2}= 0\\y_{2} = 3$

Substitute into the formula and solve;

$\frac{3 - 2 }{0 - (-8)}$

= $\frac{1}{8}$

Find the slope given the points (-5,-3) and (2,4)

Setler79 [48]

Answer:

The slope of the line is 1.

Step-by-step explanation:

We are given two coordinate points:

(-5, -3)
(2, 4)

We can use the rate of change formula to find the slope of the points.

$\displaystyle \frac{\triangle y}{\triangle x}$

In mathematics, coordinate pairs are labeled as:

$(x_1, y_1) \ \text{and} \ (x_2, y_2)$

Therefore, we can relabel our points:

$x_1 = -5$
$y_1 = -3$
$x_2 = 2$
$y_2 = 4$

After we do this, we can expand the rate of change formula:

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

Now, we can use simple substitution to solve for m, or the slope.

$\displaystyle m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{4-(-3)}{2-(-5)}\\\\m = \frac{7}{7}\\\\m = 1$

Therefore, the slope of the line is 1.

I will give brainliest 35 points The following graph represents the correlation between shoe size and height for 70 people.

Svetllana [295]

Answer:

Positive

Step-by-step explanation:

As height is increasing, shoe size is also increasing (positive slope)

Negative correlation is when one variable increases and the other decreases (negative slope)

Take the horse to overtake the

S_A_V [24]

Answer:

120 km/h

Step-by-step explanation:

Speed in one direction = 40 km/h
Speed on return = x
Average speed = 60 km/h

Let the distance be d

<u>Average speed </u>

2d/(d/40 + d/x) = 60
d/40 + d/x = 2d/60
1/40 + 1/x = 1/30
1/x = 1/30 - 1/40
1/x = (4-3)/120
1/x = 1/120
x = 120 km/h

Find the value of x. Then tell whether the side lengths from a Pythagorean triple sides 20,16 find x

Tema [17]

Answer:

x = 12

Step-by-step explanation:

Pythagorean triplet

12,16,20

So, the value of x is 12

x + 256 = 400

x = 400 - 256

x = 144

The square of 12 is 144
