write the equation of the line that passes through the point (-1,-6) and is perpendicular to a line that passes through the poin

Burka [1]

Answer:

$y=\frac{2}{3}x-\frac{16}{3}$

Step-by-step explanation:

step 1

Find the slope of the given line

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

(-2,5) and (-4,8)

substitute the values in the formula

$m=\frac{8-5}{-4+2}$

$m=\frac{3}{-2}$

$m=-\frac{3}{2}$

step 2

Find the slope of the perpendicular line to the given line

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

$m_1*m_2=-1$

$m_1=-\frac{3}{2}$ ----> slope of the given line

therefore

$m_2=\frac{2}{3}$ ---> slope of the perpendicular line to the given line

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=\frac{2}{3}$

$point\ (-1,-6)$

substitute

$y+6=\frac{2}{3}(x+1)$

step 3

Convert to slope intercept form

$y=mx+b$

isolate the variable y

$y+6=\frac{2}{3}x+\frac{2}{3}$

$y=\frac{2}{3}x+\frac{2}{3}-6$

$y=\frac{2}{3}x-\frac{16}{3}$

Find the slope of the line that contains <br>(0,4). <br>(5,0)

stich3 [128]

Answer: -4/5

Step-by-step explanation:

you can use slope formula to solve this question. （Y1-Y2）/（X1-X2）. So the answer to this question should be （0-4）/（5-0）= -4/5

Find the product 3.14 times 8

Oksana_A [137]

Answer:

25.12

Step-by-step explanation:

You would multiply 3.14 times 8 to get 2512. From there you can notice that there are 2 points after the decimal place so you need to move it over 2 places. Your final answer would be 25.12.

Alex scored 13 points in the basketball game. This was 1/5 of the total points the team scored. Write and solve an equation to d

Semenov [28]

Because alex scored 20% of the point and you would need to multiply 20% by 5 to get 100% you would multiply alexs score by 5 so 5x13=65
