(a)

Interpretation Introduction

Interpretation: The unknown values using the graph has to be predicted.

Concept Introduction:

Graph and graphing: In the equation,y=x+b where y is referred as dependent variable, x is called the independent variable, and m is the slope of the line.

Explanation

  Considertwo points: (0,20) as (x1,y1) and (0,5) as (x2,y2)y = m x + b    m = ΔyΔx= 205 = - 4  m=4,so<

(b)

Interpretation Introduction
