How do you write an equation of a line so that it is parallel or perpendicular to a given point??

The equation of a line so that it is perpendicular to a given point will be

y-y0=[tex]\frac{-1}{m}[/tex] (x - xo)

The equation of a line so that it is perpendicular to a given point will be

y-y0=m (x - xo)

The standard equation of the line is better written in point-slope form expressed as:

y-y0=m(x - xo)

where: m is the slope of the given line (x0, y0) is any point of the giuven line.

m is the slope of the given line

(x0, y0) is any point on the given line

If the given slope of the line is m, the slope of the line perpendicular will be expressed as -1/m

The equation of a line so that it is perpendicular to a given point will be

y-y0=[tex]\frac{-1}{m}[/tex] (x - xo)

what is the slope of the line with the equation: y+6=24-2x

**Answer:**

The slope is -2

**Step-by-step explanation:**

y+6=24-2x

Subtract 6 from each side

y+6-6=24-6-2x

y = 18 -2x

Rewriting

y = -2x+18

This is in slope intercept form

y = mx+b where m is the slope and b is the y intercept

The slope is -2 and the y intercept is 18

**Answer:**

A grocery store buys cereal using the cost function c(n) = { 2n when n < 100 1. 9n when 100 â‰¤ n â‰¤ 500 1. 8n when n > 500 where n is the number of boxes of cereal the grocery store buys and c(n) is the cost of the cereal. The grocery store then sells the cereal using the sales function s(c) = 1. 3c. What is the grocery store's sales from selling cereal if the grocery store buys 100 boxes and sells all of them?.

The** grocery store's sales** from **selling cereal** if the **grocery store** buys 100 boxes and sells all of them are **$247**

From the **given function**, we can see that the equivalent function for a number of **100 boxes** is given as;

c(n) = 1.9n

**If n = 100**

c(100) = 1.9(100)

c(100) = 190

Hence the cost of** 100 boxes** will be **$190 **

Given the** sales function** s(c) = 1. 3c, the grocery store's sales from **selling cereal** if the **grocery store** buys 100 boxes will be expressed as:

[tex]s(c) = 1. 3c\\s(190)=1.3(190)\\s(190)=$247[/tex]

Hence the** grocery store's sales** from **selling cereal** if the **grocery store** buys 100 boxes and sells all of them are **$247**

Mr. Capp runs his own disc golf store every Saturday. The first customer of the day came in and bought

1 driver and 2 putters for $43. The second customer came in and bought 3 drivers and 1 putter for $69.

How much money does one driver and one putter cost at Mr. C's store?

**Answer:**

a driver costs $19, while a putter costs $12

**Step-by-step explanation:**

driver = d

putter = p

1d + 2p = 43

3d + 1p = 69

d + 2p = 43. eq 1

3d + p = 69. eq 2

make d the subject of the equation

d = 43 - 2p. eq 3

substitute the value of d in eq 3 in eq 2

3(43 - 2p) + p = 69

129 - 6p + p = 69

collect like terms

129 - 69 = 6p - p

60 = 5p

p = 12

substitute the value of p in eq 3

d = 43 - 2(12)

d = 43 - 24

d = 19
