6 problems, most of them I know but I need help on these by tomorrow so high point amount
1st: Write a equation for the line that passes through the given point and has the given slope:
(12,-8) slope = -4

2nd: picture to solve
I need
A: perimeter
B: area

Ez points for you (: if you can solve this because I’m not that smart.

y = -4x - 40

Perimeter = 5x^2 + 6x + 1

Area = 20x^3 + 23x^2 - 2x - 6

Step-by-step explanation:

That's how mafia works

m = -4 is the slope

(x1, y1) = (12, 8) is a point on the line

The point-slope form is:

y - y1 = m(x - x1)

y - 8 = (-4)(x - 12)

The slope-intercept form is:

y = 8 + (-4)x + 16

y = (-4)x + 24

The standard form is:

y + (-4)x = 18 multiply both sides by 4

-4x = 18*4

-4x  = 72

Step-by-step explanation:

2) Perimeter = 5x^2 + 2x -2

=7x^2 -2

L =49x -2

W=4x+3

 49 -2 =47 x 16+3  = 19  

A = 47x19

A = 893

P= 47+47+19+19= 132
