Find the equation of the line with a slope of 4 and passing through (0,3)

4x -  y + 3 =0 is the equation of the line

Step-by-step explanation:

Given:

The slope of the line  =  5

The points through with the line passes = (0,3)

To Find:

The equation of the line  =?

Solution:

The equation  y = mx + b

where m is the slope and (0,b) is the y-intercept.

The slope is given which is m = 4 and a point (0,3)

Then you can use slope-point equation

where is the given point

y - (3) = 4(x - 0)

y - 3 = 4(x)

y = 4x - 22

y - 3 = 4x

4x - y + 3 = 0

The equation of the line with a slope of 4 and passing through (0,3) is

4 x - y + 3 = 0

Explanation:

Slope, m = 4

Points = ( 0,3 ) -  (, )

Equation of the line = ?

We know,

The formula used to find the equation of a line when points and slope are given is

                                            (y - ) = m ( x - )

Where, and are the points

            m is the slope

Therefore,

y - 3 = 4 ( x - 0)

y - 3 = 4 x

4 x - y + 3 = 0

Therefore, The equation of the line with a slope of 4 and passing through (0,3) is 4 x - y + 3 = 0

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
