Answer:

The equation would be -x + 4y = -8

Step-by-step explanation:

To find the standard form of the line, solve for the constant.

y - 1 = 1/4(x - 12)

y - 1 = 1/4x - 3

-1/4x + y - 1 = -3

-1/4x + y = -2

-x + 4y = -8

Answer: The standard equation of this line is x-4y=8.

Step-by-step explanation:

Since we have given that

Two coordinates are as follows:

(-4,-3) and (12,1)

So, slope would be

\dfrac{y_2-y_1}{x_2-x_1}\\\\\\=\dfrac{1-(-3)}{12-(-4)}\\\\\\=\dfrac{1+3}{12+4}\\\\\\=\dfrac{4}{16}\\\\\\=\dfrac{1}{4}

So, the standard form of equation of this line is given by

y-y_1=\dfrac{1}{4}(x-x_1)\\\\y-(-3)=\dfrac{1}{4}(x-(-4)\\\\y+3=\dfrac{1}{4}(x+4)\\\\4(y+3)=x+4\\\\4y+12=x+4\\\\4y=x+4-12\\\\4y=x-8\\\\-x+4y=-8\\\\x-4y=8

Hence, the standard equation of this line is x-4y=8.

a merchant buys a telivision for $125 and sells it for the reatail price of $200. what is the markup.
NISA [10]
Before going to the answer, let's first understand what a mark up is. The mark up is the amount that the seller will add to the purchase cost to the retail cost so that he can earn a profit. So the purchase cost of the television is 125 dollars, and the selling cost or retail cost of the television is 200 dollars. So what is the markup. Simply minus 125 dollars from 200 dollars and you will get the amount added to the purchase cost or simply the mark up. So 200 dollars - 125 dollars is 75 dollars. So 75 dollars is the markup that the merchant put on the television

A caterpillar started at point (−2.5, −5.5) on a coordinate plane. She crawled in a straight line through the origin to point (4
alexgriva [62]

Answer:

The value of y is 99

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem the line passes through the origin

therefore

Is a proportional variation

Find the value of k

with the point (-2.5,-5.5)

k=y/x=-5.5/-2.5=2.2

The equation is equal to

y=2.2x

so

For x=45

substitute

y=2.2(45)=99
