Answer:
C
Step-by-step explanation:
Answer:
9 sq ft
Step-by-step explanation:
The slope-intercept form:

m - slope
b - y-intercept → (0, b).
We have the points (4, 7) and (0, 7) → b = 7.
Calculate the slope:

Therefore we have 
The standard form: 
<h3>Answer: y = 7.</h3><h3><em>It's a horizontal line.</em></h3>
First we do brackets
(8900)-(1x89)
next we do the next bracket
8900-89
now we finish the equation
8811
