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.  

as

\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

Whats -7/3(x-1)+2=4(2-x) equals
olga55 [171]
Expand: -7/3(x-1)+2: 13/3-7x/3
expand: 4(2-x): 8-4x
13/3 - 7x/3 =8-4x
13/3 -7x/3 -13/3 = 8-4x -13/3
-7x/3=-4x+11/3
-7x/3 * 3= -4x*3+11/3*3
-7x=-12x+11
-7x+12x=-12x+11+12x
5x=11
5x/5=11/5
x=11/5

4/5 = _/30<br><br> Fill in the blank to make the two fractions equivalent.
Sergio039 [100]

Answer:

4/5=24/30

Step-by-step explanation:

If we know we must multiply 5 by 6 to get 30 as the denominator, we must also multiply the numerator by 6 to get an equivalent fraction. Four multiplied by six is 24.
