Lines K and N are perpendicular If the slope of line K is -6, what is the slope of Line N

djverab [1.8K]

line N has slope m = $\frac{1}{6}$

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

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

thus line N has slope - $\frac{1}{- 6}$ = $\frac{1}{6}$

Irina18 [472]

Answer:

Her weekly allowance is $8.

Step-by-step explanation:

Let the weekly allowance of Ming is $x.

If she spends half of her weekly allowance playing mini-golf and to earn more money her parents let her wash the car for $5, then the remaining amount of money that she has = $(\frac{x}{2} + 5)$ dollars.

Now, given that $(\frac{x}{2} + 5) = 9$

⇒ $\frac{x}{2} = 4$

⇒ x = $8

Therefore, her weekly allowance is $8. (Answer)

Write an equation in Standard Form of the line passing through (5, -4) with a slope of -2/5.

beks73 [17]

Answer:

The answer is

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

$y - y_1 = m(x - x_1)$

where

m is the slope

( x1 , y1) is the point

From the question the points is (5, -4) and slope - 2/5

The equation is

$y + 4 = - \frac{2}{5} (x - 5) \\ y + 4 = - \frac{2}{5} x + 2 \\ y = - \frac{2}{5} x + 2 - 4$

We have the final answer as

$y = - \frac{2}{5} x - 2 \\$

Hope this helps you
