Answer:
y = - 2x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (1, - 1) and (x₂, y₂ ) = (2, - 3) ← 2 ordered pairs from the table
m =
=
= - 2 , then
y = - 2x + c ← is the partial equation
To find c substitute any ordered pair from the table into the partial equation
Using (3, - 5 ) , then
- 5 = - 6 + c ⇒ c = - 5 + 6 = 1
y = - 2x + 1 ← equation of line
System c, plan out a variable system as the first buy, is 5 peaches and two watermelons, totaling to 7.75$, then the second buy is 3 watermelons and 4 peaches, totaling to 10.95$, system c is the only system that matches up
Let width be x,
Length: 3+x
P=2(l+w)
54=2(x+(x+3))
54/2=2x+3
27=2x+3
27-3=2x
24=2x
24/2=x
12=x
Therefore, the width is 12 inches and the length is (12+3)=15 inches
