What equation in slope-intercept form represents the line that passes through

gregori [183]

Answer:

So, equation in slope-intercept form that represents the line that passes through the points (1,3) and (2,5) is y=2x+1

Step-by-step explanation:

We need to write equation in slope intercept form that represents the line that passes through the points (1,3) and (2,5)

The standard equation of slope-intercept form is: y= mx+b

where m is the slope of the lines and b is the y-intercept.

To make the equation we need to find slope (m) and y-intercept (b)

Find Slope

The formula to find slope m is: $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

We have $x_{1}=1, x_{2}=2, y_{1}=3\ and \ y_{2}=5$

Putting values in the formula to find slope

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\m=\frac{5-3}{2-1}\\m=\frac{2}{1}\\m=2$

So, value of slope m is m=2

Find y-intercept

Using formula of slope-intercept formula we can find b

y=mx+b

Using point (1,3) (where x=1 ,y=3) and slope m=2

$3=2(1)+b\\3=2+b\\b=3-2\\b=1$

So, value of y-intercept b is: b=1

Required equation in Slope Intercept Form

We have slope m = 2 and y-intercept b=1

$y=mx+b\\y=2x+1$

So, equation in slope-intercept form that represents the line that passes through the points (1,3) and (2,5) is y=2x+1

A mesuré of_____ for a numerical data set summerizes all of its values with a single number????

hammer [34]

Answer:

Center

Step-by-step explanation:

A numerical data can be defined as a data set that is expressed in numbers only or a data set consisting of numbers rather than words. A numerical data is also known as a quantitative data.

Basically, numerical data are classified into two (2) main categories and these are;

1. Discrete data: a discrete data is a data set in which the number of possible values are either finite or countable. For instance, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.

2. Continuous data: a continuous data is a data set having infinitely many possible values and those values cannot be counted, meaning they are uncountable. Any quantity such as height, volume, weight, density, length, pressure, temperature, speed, distance, time are generally a continuous data.

A measure of center for a numerical data set summerizes all of its values with a single number.

On the other hand, a measure of variation gives a description of how the values of a numerical data varies with a single number.
