Q # 9 help please:The table shows the height of a plant as it grows.What equation in point-slope form gives the plant's height a

ivanzaharov [21]

Answer: First option. y-15=5(x-3)

Solution:

We can take any pair of points of the table. For example:

P1=(3, 15)=(x1, y1)→x1=3, y1=15

P2=(5, 25)=(x2,y2)→x2=5, y2=25

And we can find the slope m using the following formula:

m=(y2-y1)/(x2-x1)

m=(25-15)/(5-3)

m=(10)/(2)

m=5

Now we can apply the point-slope formula to find the equation of the right line:

y-y1=m(x-x1)

Replacing y1=15, m=5, and x1=3

y-15=5(x-3)

$\large \bold {ANSWER}$

$\implies \boxed{\underline{\huge{\tt{\orange{\: \: 9\% \: \: }}}}}$

9% of the family income is being spent to pay the energy bill.

$\large \bold {SOLUTION}$

<h2>HOW TO FIND OUT THE PERCENTAGE?</h2>

If your income is now $2,000.00 and you have withdrawn $180.00 from the value, then we say that the $2,000.00 is equivalent to 100% of the value, that is, the total amount. And the amount that was withdrawn will be X because we still don't know how much percent is equivalent to $ 180.00 of this value.

To solve, we will use the simple rule of three like this:

$\frac{2000}{180} = \frac{100}{x}$

With this we will multiply the denominator of one with the numerator of the other, being:

2000 * X and 180 * 100
Where: 2000 * x is equal to 2000x
And 180 * 100 is equal to 18,000

Knowing this, we will solve it this way:

2000x = 18,000

To start we will isolate the unknown(x) from the values taking the 2000 to the other side of the equality turning it into the denominator of 18,000.
