A function that fits the following points (0,5), (2,-13) is y = 9x + 5

<h3>Equation of a line</h3>

The equation of a line in slope-intercept form is expressed as;

y =mx +b

where;

m is the slope

b is the intercept

Given the following coordinates (0,5), (2,-13)

Slope = -13-5/2-0
Slope = -18/-2

Slope = 9

Since the y-intercept is b = 5, hence the equation of the line will be y = 9x + 5

arsen [322]

We know that
<span>20% --------------> were blue
</span><span>1/10---> 0.10----> 10%--------------> were white
</span><span>40% ---------------> were silver
</span>
and
<span>9 ---------> were gold
so
gold=100%-(20%+10%+40%)-------> 100%-70%------> 30%

30% ---------------------> is equal to 9
10% (</span>were white)<span>-------> X
X=10%*9/30%------> x=3

the answer is
3</span>

igomit [66]

5 is a constant - you pay $5 before you go on any of the waterslides.
let the number of waterslides Steven went on = x

5 +2x =17 ($5 plus $2 per waterslide ride = 17)

Answer a is correct.
By the way, Steven went on 6 waterslide rides.

An expression that uses variables to state a rule is a ______

nikdorinn [45]

<u>Formula</u>

<em>An expression that uses variables to state a rule is a </em><u><em>formula</em></u>

<h2>Explanation:</h2>

An expression that uses variables to state a rule is a formula. It's important to know that formulas uses the equals sign (=) and includes two or more variables. Formulas gives us information that we express symbolically. For example, the well known formula for the volume of a sphere is defined as:

$V=\frac{4}{3} \pi r^3 \\ \\ \\ Where: \\ \\ V:Volume \ of \ the \ sphere \\ \\ r:Radius \ of \ the \ sphere$

So in this formula we have a relationship between the volume of a sphere and its radius, so if we have information about the radius of it we can easily calculate the volume of it.
