Write an equation of a line perpendicular to y=3x+5 that contains the points (-3,-4)
Vlad [161]

The equation of line is:

y = - \frac{1}{3}x-5

Further explanation:

Given equation of line is:

y = 3x+5

The standard form of point-slope form is:

y = mx+b

Comparing the given equation with the standard form is:

m = 3

We know that product of slopes of two perpendicular lines is -1

Let m2 be the slope of line perpendicular to y = 3x+5

Then

3 * m_2 = -1\\m_2 = -\frac{1}{3}

Putting the value of slope in standard form

y = -\frac{1}{3}x + b

To find the value of b, putting (-3,-4) in equation

-4 = -\frac{1}{3}(-3) + b\\-4 = 1 + b\\b = -4-1\\b = -5

Putting the values of slope and b in equation

y = - \frac{1}{3}x-5

Keywords: Slope, Point-intercept form

How do you find the volume of a sphere when the circumference is 16.25
muminat
The formula for Circumference is C= πd (with C being Circumference and D being diameter). You would substitute the information into the equation, to find the diameter. After, finding the diameter divide it by 2 to find the radius. When you find the value of the radius, substitute it into the equation (v=4/3πr^3). Volume equals 4 divided by 3, times pi, times the radius cubes (to the power of 3).

Yes, Dean is correct.

13% = 13/100 = 0.13

0.1 = 0.10
