Find the equation of the line. Use exact numbers.

Veseljchak [2.6K]

Answer:

Step-by-step explanation:

(-6,0) ; (0,4)

$Slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{4-0}{0-(-6)}\\\\=\frac{4}{6}\\\\=\frac{2}{3}$

y - y1 = m(x -x1)

y - 0 = (2/3)(x- [-6] )

y = (2/3)(x + 6 )

$y=\frac{2}{3}x + \frac{2}{3}*6\\\\y=\frac{2}{3}x+2*2\\\\y=\frac{2}{3}x + 4\\$

PLEASE HELP ILL GIVE BRAINLIEST!!!! I AM STUMPED AS I HAVE NOT PAYED ANY ATTENTION IN CLASS PLEASE HELP ME!!!!

Svetlanka [38]

Answer:

$y=\frac{-2}{3} x-15$

Step-by-step explanation:

First draw a line. I will put it in an attachment so you can see the line.

Now choose to points on the line to use the slope formula.

(0,15) and (3,13).

Slope formula: $\frac{y2-y1}{x2-x1}$

Plug in the information needed using the two points chosen.

$\frac{13-15}{3-0}=\frac{-2}{3}$

The slope is $\frac{-2}{3}$ .

Now use point-slope formula.

Point-slope formula: y-y1=m(x-x1)

y-15= $\frac{-2}{3}$ (x-0)

y-15= $\frac{-2}{3}$ x-0

Subtract 15 from both sides.

y= $\frac{-2}{3}$ x-15

Hope this helps!

If not, I am sorry.

PLEASE HELP! ITS DUE TODAY!!!

arlik [135]

Answer:

Step-by-step explanation:

1.24 * 0.15 = 0.0186

As you can see, the numbers are the same, but the order of the decimal is different.

Since the order of the decimal is different, so will the answer.

1,860 and 0.0186 do have the same numbers in them, but since the decimal is located in different spots, then the answer will be different with different values.

You might not see the decimal in 1,860, but it is after the 0.....

1,860.0 ( same thing just added a decimal, but it is the same value)

Hope this helped!

Which shows the following expression after the negative exponents have been eliminated?

gregori [183]

Answer:

The correct answer option is $\frac {a ^ 3 b^4 } {a b^2}$ .

Step-by-step explanation:

We are given the following expression and we are to figure out which of the given answer options show the expression after the negative exponents have been eliminated:

$\frac {a^3 b^{-2}} {a b^{-4}}$

When negative exponent changes sign, then it moves from numerator to denominator or from denominator to numerator.

$\frac {a^3 b^4} {ab^2}$
