' This is kind of like the SAS, or side-angle-side postulate. But SAS requires you to know two sides and the included angle.

Answer:

Step-by-step explanation:
From the question we are told that
February Heat
February Gas 
April Heat
April Gas 
Generally equation for heating degree-days X is mathematically given by



Generally the equation for gas bill Y is mathematically represented by

The equation representing the relationship between the gas bill (Y) and heating degree-days (X) is

Step-by-step explanation:
first u need to pick a random coordinate to substitute the X . example 0
y = 2(0) + 1
y =1 , X= 0
X= 1
y= 2(1) + 1
y= 3, X= 1
then you continue this same process and again until u have at least two points to draw a straight line. it kinda depended if u want to fill the entire graph.
