Use the following graph to answer the following question: (a) What is the value of x when y=4.0? (b) What is the value of y when x = 3.0? (c) What are the slope and the y-intercept of the line? (d) What is the value of y when x= 1.0? (a)

Interpretation Introduction

Interpretation: The unknown values using the graph 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

The value of x is calculated as,

Considertwo points: (0.05,1.0) as (x1,y1) and (0,0) as (x2,y2)slope:x-x1y-y1=x1-x2y1-y2            x - 0.05y -1.0 = 0.05 - 01.0 - 0             x - 0
