Find the equation of the line below (mathswatch)

Equation of line is 2x - y +3 = 0

Step-by-step explanation:

A graph is given to us. And we need to find the equation of the line. From the graph we can seethat the graph passes through the point (0,3) . So the y intercept is 3 . Now let's find the slope of the line so as to use the slope Intercept form which is y = mx + C .

Here ,

From the graph we can see that the distance between points (2,7) & (2,3) is 4. And the distance between the points (2,3) & (0,3) is 2. So let's find the slope of the line. We know that the slope of the the line is tanθ .

⇒ Slope = tanθ

⇒ Slope = y2 - y1/ x2 - x1

⇒ Slope = 4/2

⇒ Slope = 2

Hence the slope of the line is 2 .

Using Slope intercept form :-

⇒ y = mx + C

⇒ y = 2*x + 3

⇒ y = 2x + 3

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.  

there still no table
