Answer:

ac = 18.5

Step-by-step explanation:

perimeter of a rectangle = $2(l+b)$

= 138m^2= 2(2x + 6 ) + 52

= 4x + 12 + 52 = 138

= 4x + 64 = 138

= 4x = 138 - 64

= 4x = 74

= x = 74/4

= x = 18.5

ANSWER

$y = - 2x - 5$

EXPLANATION

We can use any two points to determine the slope.

The line passes through;

(-3,1) and (-5,5).

The slope is given by

$m = \frac{y_2-y_1}{x_2-x_1}$

This implies that;

$m = \frac{5 - 1}{ - 5 - - 3}$

$m = \frac{4}{ - 2} = - 2$

We can now find the equation using the formula;

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

$y - 1 = - 2(x + 3)$

Expand:

$y = - 2x -6 + 1$

$y = - 2x - 5$
