Write the equation of a line perpendicular to y = -5/6x -3 and whose y-intercept is (0,11). I fr need help..

Sloan [31]

Hey!

A perpendicular line has the slope as the negative reciprocal of the given line, so therefore the new lines slope would be...

y = 6/5x + b

Now to find the y-intercept you will have to just plug in the given point/coordinate in the equation above and solve for b...

11 = 6/5(0) = b

11 = b

Put the given slope and y-intercept in a slope intercept form equation (slope intercept form is y = mx + b)...

y = 6/5x + 11

This new equation is:

1) perpendicular to the given equation

2) in slope intercept form

Answer: y = 6/5x + 11

Hope this Helped!

Determine if line KM and line ST are ॥, ⊥, or neither: K(-5,1) , M(-2,-8), and S(12,14), T(20,-10) Parallel Perpendicular or nei

Black_prince [1.1K]

Answer:

The lines are parallel i.e. KM || ST

Step-by-step explanation:

Given

K(-5,1) , M(-2,-8), and S(12,14), T(20,-10)

In order to find if the lines are parallel, perpendicular or neither slope will be used.

The slope of any line which passes from two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by the formula

$m = \frac{y_2-y_1}{x_2-x_1}$

If two lines are parallel their slope is equal. If two lines are perpendicular the product of their slope is equal to -1

So, first slopes of both lines will be calculated.

Let m1 be the slope of KM

and

m2 be the slope of ST

In case of KM:

$(x_1,y_1) = (-5,1)\\(x_2,y_2) = (-2,-8)$

Putting the values in the formula for slope

$m_1 = \frac{-8-1}{-2-(-5)}\\m_1 = \frac{-9}{-2+5}\\= \frac{-9}{3}\\= -3$

In case of ST:

$(x_1,y_1) = (12,14)\\(x_2,y_2) = (20,-10)$

Putting the values in the formula for slope

$m_2 = \frac{-10-14}{20-12}\\= \frac{-24}{8}\\= -3$

As we can see that slope of both lines KM and ST are equal

i.e. m1 = m2 = -3

Hence,

The lines are parallel i.e. KM || ST
