(-2,-4) ;m =3 in point slope form please

zalisa [80]

$\huge\boxed{y+4=3(x+2)}$

Point-slope form is $y-y_1=m(x-x_1)$ , where $m$ is the slope and $(x_1,y_1)$ is a point on the line.

Substitute in the values. $y-(-4)=3(x-(-2))$

Simplify the negative subtraction to addition. $\boxed{y+4=3(x+2)}$

Subtract 3/y-2 - 1/y+3

Helen [10]

To subtract fractions, we need a common denominator.

$\frac{3}{y-2}$ - $\frac{1}{y+3}$

the common denominator will be (y-2)(y+3)

$\frac{3(y+3)-1(y-2)}{(y-2)(y+3)}$
$\frac{3y + 9 - y + 2}{(y-2)(y+3)}$
$\frac{2y + 11}{(y-2)(y+3)}$

The answer above will be the simplified form.
