Equation of the graph is y = –9x + 360.
Solution:
Take any two points on the line.
Let the points are (40, 0) and (0, 360).
Slope of the line:
m = –9
The slope is –9.
y-intercept is the point where the line intersects with the y-axis.
y-intercept = 360
b = 360
Slope-intercept form:
y = mx + b
y = –9x + 360
Equation of the graph is y = –9x + 360.

Answer:
The length of the rectangle is 7x + 27
Step-by-step explanation:
Given;
area of the rectangle, A = 21x + 81 units²
width of the rectangle, w = 3 units
let the length of the rectangle, = L
Area of the rectangle = length x width
A = L x w
21x + 81 = 3L
L = ¹/₃(21x + 81)
L = 7x + 27
Therefore, the length of the rectangle is 7x + 27
