Chapter 4.2, Problem 1STP

For Exercises $1-4,$ choose the correct letter.

Which equation represents the relationship shown in the table at the right?

A. $y=-x-3$

C. $y=2x-3$

B. $y=x-3$

D. $y=-2x+3$

To determine

To find: Let’s use y=mx+b. Where ‘m’ is slope of the line and ‘b’ is y intercept.

Answer to Problem 1STP

C. $y=2x-3$

Explanation of Solution

Given information: We are given with table of values (0,-3) , (1, -1) , (2,1) and (3,3)

Calculation:

Let’s find the difference of y values ,

-1-(-3) =2

1-(-1)=2

So, slope $m=2$

And we have (0,-3), so y intercept is -3.

Equation is $y=2x-3$
