Determine the standard form of the equation of the line that passes through (-2, 0) and (-8,5)

Naya [18.7K]

Answer:

$-5x-6y=10$ ← in standard form

Step-by-step explanation:

The equation of a line in standard form is.

$Ax+By=C$

were

A is a positive integer and

B, C are integers

As the equation in point-slope form

$y-y_1=m\left(x-x_1\right)$

where m is the slope and $\left(x_1,\:y_1\right)$ is a point on the line.

$\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(-2,\:0\right),\:\left(x_2,\:y_2\right)=\left(-8,\:5\right)$

$m=\frac{5-0}{-8-\left(-2\right)}$

$m=-\frac{5}{6}$

using $m=-\frac{5}{6}$ and $\left(x_1,\:y_1\right)=\left(-2,\:0\right)$ then

$y-0=-\frac{5}{6}\left(x-\left(-2\right)\right)$

$-\frac{5}{6}\left(x-\left(-2\right)\right)=y-0$

$6\left(-\frac{5}{6}\left(x-\left(-2\right)\right)\right)=6y$

$-5\left(x+2\right)=6y$

$-5x-10=6y$

$-5x-6y=10$ ← in standard form

What is the reciprocal of 17

Alla [95]

Since 17 in fraction form is 17/1, the reciprocal of that would be just flipping it, so the demominator is on the top and numerator is on the bottom.

The reciprocal of 17 is 1/17.

HELP! I don’t know what to do for #4. well i don’t know what to put for another equation. i Dont need help solving i just need h

OLga [1]

Let s = #small notebooks

Let L = #large notebooks

We Can set up two equations from the info given.

s + L = 6 bought 6 notebooks total

8s + 10L = 56 spent $56

Solve equation 1 for one variable.

L = 6-s

Plug 6-s in equation 2 in place of L

and solve for s

8s + 10(6-s) = 56

8s + 60 - 10s = 56

-2s + 60 = 56

-2s = -4

s = (-4)/(-2)

s = 2

We know s+L = 6 and s=2

2+L = 6

L = 4

4 large notebooks and 2 small notebooks

Which expression is equivalent to 5^-2 x 5^-1

Mrac [35]

When you multiply powers with the same base, you sum the exponents:

$a^b\times a^c=a^{b+c}$

So, in this case, you have

$5^{-2}\times 5^{-1}=5^{-2-1}=5^{-3}$
