LW = A
L(L - 3) = 18
L^2 - 3L - 18 = 0
(L - 6) (L + 3) = 0
L could be 6 or -3 ( -3 cannot be a length of a side of a rectangle since it’s negative.)
So L = 6 and W= 3

Which point-slope equation represents a line that passes through (3, –2) with a slope of -4/5?

alexira [117]

Answer:

$y+2=-\frac{4}{5}(x-3)$

C is correct equation.

Step-by-step explanation:

We are given a point and slope of a line. Using point slope form formula to find the equation of line and match the correct option.

Formula:

$y-y_1=m(x-x_1)$

where,

$slope (m)=-\frac{4}{5}$

$Point:(x_1,y_1)\rightarrow (3,-2)$

Equation of line:

$y-(-2)=-\frac{4}{5}(x-3)$

$y+2=-\frac{4}{5}(x-3)$

Thus, C is correct equation of given information.
