Answer:

<h2><em><u>88 ft.</u></em></h2>

12 Ft. (Width) · 9 Ft. (Length)

= 108 Ft.

  • Find The Area Of The Door

2.5 Ft. (Width) · 8 Ft. (Length)

= 20 Ft.

What is the slope and y-intercept of y+3= -1/3
bazaltina [42]

Assuming this is written correctly, with no x in the equation, we just solve for y:

y = -3 - 1/3 = -10/3 = 0 x - 10/3

That's slope-intercept form.
