Answer:

y=3

Step-by-step explanation:

y-y1=m(x-x1)

y-3=0(x-(-12))

y-3=0(x+12)

y-3=0

y=0+3

y=3

Answer:

Step-by-step explanation:

If a line has slope 0, then it's a horizontal line.

A horizontal line has an equation:

where a is any real number.

The line passes through point (-12, 3) → x = -12, y = 3.

Therefore the equation is

$\bf ~~~~~~~~~~~~\textit{function transformations}\\\\\\f(x)= A( Bx+ C)+ D\\\\~~~~y= A( Bx+ C)+ D\\\\f(x)= A\sqrt{ Bx+ C}+ D\\\\f(x)= A(\mathbb{R})^{ Bx+ C}+ D\\\\f(x)= A sin\left( B x+ C \right)+ D\\\\--------------------\\\\\bullet \textit{ stretches or shrinks horizontally by } A\cdot B\\\\\bullet \textit{ flips it upside-down if } A\textit{ is negative}$

$\bf ~~~~~~if\ \frac{ C}{ B}\textit{ is positive, to the left}\\\\\bullet \textit{ vertical shift by } D\\~~~~~~if\ D\textit{ is negative, downwards}\\\\~~~~~~if\ D\textit{ is positive, upwards}\\\\\bullet \textit{ period of }\frac{2\pi }{ B}$

with that template in mind,

$\bf y=\stackrel{A}{1}|\stackrel{B}{1}x\stackrel{C}{+1}|\stackrel{D}{-2}$

so is really just |x| but shifted some,

C/B = 1/1 = +1, horizontally to the right by 1 unit.

D = -2, vertically downwards by 2 units.

The table below shows the linear relationship between the number of people at a picnic and the total cost of the picnic.

8_murik_8 [283]

The true statements are:

The independent variable is the number of people.
The rate of change is $8.67 per person.
As the number of people increases, the total cost of the picnic increases.

<h3>What are the true statements?</h3>

The independent variable is the variable that determines the value of the dependent variable. There is a positive relationship between the number of people at the picnic and the total cost. This is because it can be seen as the number of people at the picnic increases, the total cost changes.

Rate of change = total cost / number of people

$52 / 6 = $8.67

Step-by-step explanation: A coordinate grid has two perpendicular lines, or axes (pronounced AX-eez), labeled just like number lines. The horizontal axis is usually called the x-axis. The vertical axis is usually called the y-axis. The point where the x- and y-axis intersect is called the origin

-35 − (-12) = A) -47 B) -23 C) 23 D) 47

Alexus [3.1K]

B) -23 because a double negative is a positive so it’s -35 + 12 which is -23
