A given line has the equation 2x + 12y = −1. What is the equation, in slope-intercept form, of the line that is perpendicular to
VikaD [51]

Answer:

y = 6x + 9

Step-by-step explanation:

The equation of a line in slope- interceot form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 2x + 12y = - 1 into this form

Subtract 2x from both sides

12y = - 2x - 1 ( divide all terms by 12 )

y = - \frac{1}{6} x - \frac{1}{12} ← in slope- intercept form

with slope m = - \frac{1}{6}

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{-\frac{1}{6} } = 6

Note the line passes through (0, 9) on the y- axis ⇒ c = 9

y = 6x + 9 ← equation of perpendicular line

PtichkaEL [24]

Answer:

74.36 m^2 is the total flooring area in m^2.

Step-by-step explanation:

10 - 8 by 10 ft kitches comes to 800 ft^2.  We need to convert this to m^2.  Recall that 1 m = 3.28 ft.  From this we know that (1 m)^2 = (3.28 ft)^2 = 10.76 ft^2.

Multiply 800 ft^2 by the conversion factor  (1 m)^2 / 10.76 ft^2.  We get:

74.36 m^2.

What is the equation?
Nana76 [90]

Answer:

y=-2+4

Step-by-step explanation:

we know the y intercept is four, so we can plug that into y=mx+b

so far we know y=mx+4

and the equation for finding slope is \frac{y_{2} -y_{1} }{x_{2} -x_{1} }

so let's find two points on the graph

let's make it easy on ourselves and use the points laid out for us

(0,4) and (2,0)

\frac{0-4}{2-0}

solving that would come out to be \frac{-4}{2}

simplified, that would be -2

now that we know the slope, we can put them into slope-intercept form

y=-2+4
