Round to the nearest hundredths
Fofino [41]
4 units because the y-intercept is how you figure out the difference. You take the y-intercept, find the absolute value of it, and you found the distance of the line! This is of course considering the lines are parallel, meaning the slope is the same.

What is the value of x<br><br> 1/5 = 25/x
Mama L [17]
First getting x as a numerator rather than a denominator. Then grouping like terms by moving 5 from the left side to the right. Work below:
\frac{1}{5} = \frac{25}{x} \\  \frac{1}{5}*x = \frac{25}{x}*x\\ \frac{1}{5}x = 25\\\frac{1}{5}x * 5 = 25*5\\x=125

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)

so

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}
