Textbook Problem

# 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,

â€‚Â Considerâ€‰twoÂ points:Â (0.05,1.0)Â asÂ (x1,y1)Â andÂ (0,0)Â asÂ (x2,y2)slope:x-x1y-y1=x1-x2y1-y2Â Â Â Â Â Â Â Â Â Â Â Â xÂ -Â 0.05yÂ -1.0Â =Â 0.05Â -Â 01.0Â -Â 0Â Â Â Â Â Â Â Â Â Â Â Â Â xÂ -Â 0
