Given the line 2x - 3y - 5 = 0, find the slope of a line that is perpendicular to this line.

Mathematics

Tasya [4]3 years ago

Answer:  

The slope of a line that is perpendicular to the given line is -\frac{3}{2}

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope of the line and "b" is the y-intercept.

Solve for "y" from the equation of the line 2x - 3y - 5 = 0:

2x - 3y - 5 = 0\\\\-3y=-2x+5\\\\y=\frac{-2}{-3}x+\frac{5}{-3}\\\\y=\frac{2}{3}x-\frac{5}{3}

You can observe that the slope of this line is:

m=\frac{2}{3}

By definition, the slopes of perpendicular lines are negative reciprocal, then, the slope of a line that is perpendicular to the give line, is

m=-\frac{3}{2}

Only applies if all the books are either English or French

Please help!! the table shows the number of hours that a group of friends spent in their first week training to run a marathon.
saw5 [17]
So if they all add 4 hours to their time then they have:
Jeff 9
Mark 14
Karen 9
Costas 13
Brett 11
Nikki 9
Jack 11

so now to find the mean you add all the numbers together to get 76 and then you divide it by the number of people (7 people) so 76 divided by 7 equals 10.8571429 and that's the mean.

Now to find the median you put all the numbers in order from least to greatest: 9;9;9;11;11;13;14 and you take the number in the middle but since both 11 and 11 are in the middle you take the mean of them and the mean of them is 11 so the median of the numbers is 11

now to find the range you take the largest number (14) and you subtract the smallest number (9) so 14 - 9 is 5 so 5 is the range

and last the mode is the number that is repeated most out of all the numbers so the mode would be 9
