Answer:

y = 4/5x - 9/5

Step-by-step explanation:

4x - 5y = 9 to solve for y you get it by itself.

-4x -4x minus 4x from both sides

-5y = - 4x + 9

/-5 /-5 Divide both sides by 5

y = 4/5x - 9/5 because -4/-5 is 4/5 and 9/-5 is - 9/5

Rewrite the equation y−2=−3/2(x+6) in standard form.

navik [9.2K]

For this case we have that by definition, the standard form of the equation of the line is given by:

$ax + by = c$

We have the following equation:

$y-2 = - \frac {3} {2} (x + 6)$

We manipulate the equation algebraically:

$y-2 = - \frac {3} {2} x- \frac {3 * 6} {2}\\y-2 = - \frac {3} {2} x \frac {18} {2}\\y-2 = - \frac {3} {2} x-9\\y-2 + 9 = - \frac {3} {2} x\\y-7 = - \frac {3} {2} x\\2 (y-7) = - 3x\\2y-14 = -3x\\3x + 2y = 14$

Finally, the equation is:

$3x + 2y = 14$

Answer:

$3x + 2y = 14$
