Answer:
y = - 3x - 3
Step-by-step explanation:
the equation of a linear function in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
To calculate m use the slope formula
m = (y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 2, 3) and (x₂, y₂ ) = (6, -21) ← 2 points from the table
m = 
= 
= - 3
y = - 3x + b ← is the partial equation
To find b substitute any other point from the table into the partial equation
using (2, - 9), then
- 9 = - 6 + b ⇒ b = - 9 + 6 = - 3
y = - 3x - 3 ← linear relationship
Because the surface area is of a 2-D SHAPE to find a area of a 2-D shape is l x w
The point (1, 20) means that the total money spent for purchasing one ticket is $20.
<h3>
Linear equation</h3>
Linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Let y represent the total money spent for buying x number of tickets.
The point (1, 20) means that the total money spent for purchasing one ticket is $20.

Answer:
3(12+27)
Step-by-step explanation: 3 can go into both of those numbers so u would just divide that by 3 with 36 and 81.
