To find the slope of this line we will use the slope formula, which is:

$m = \dfrac{y_2 - y_1}{x_2 - x_1}$

(Where $(x_1, y_1)$ and $(x_2, y_2)$ are points on the line)

To find our answer to this problem, we can simply substitute the values we are given:

$m = \dfrac{-16 - (-8)}{-8 - (-10)} = \dfrac{-16 + 8}{-8 + 10} = \dfrac{-8}{2} = -4$

The slope of the line is -4.

A bag contains 150 marbles. Some are blue, and the rest are white. There are 21 blue marbles for every 4 white marbles. How many

Olin [163]

Given:

Total number of marbles in the bag = 150

There are 21 blue marbles for every 4 white marbles.

To find:

The number of blue marbles in the bag.

Solution:

Since, there are 21 blue marbles for every 4 white marbles, therefore the ratio of blue marble to white marbles is 21:4.

Let the number of blue marbles be 21x and white marbles be 4x.

Total number of marbles in the bag = 150

$21x+4x=150$

$25x=150$

Divide both sides by 25.

$x=\dfrac{150}{25}$

$x=6$

Now,

$\text{Blue marbles}=21x$

$\text{Blue marbles}=21(6)$

$\text{Blue marbles}=126$

Therefore, the number of blue marbles is 126.

What is the slope of a line that has an x-intercept of 6 and a y-intercept of 0

ankoles [38]

x intercept of 6 means (6,0) is on the line

y intercept of 0 means (0,0) is on the line

so the slope is (0-0)/(6-0) = 0

Answer: 0

Note: The question is actually bad; the line through the origin with slope zero is the X axis itself in which case it wouldn't be right to call the X intercept (just) (6,0).
