Chapter 4.7, Problem 40PPS

To determine

To Find:

The equation of the graph from the given options.

Answer to Problem 40PPS

Option A is correct match.

Explanation of Solution

Given Information:

The graph is :

  

Concept Used:

LINEAR FUNCTION :

It is represented by a line on the graph.

Equation of slope-intercept form of a line is given by:

  $y=mx+b\mathrm{............................}(1)$

Where

  $\begin{array}{l}b=y-\mathrm{int}ercept\\ m=\frac{rise}{run}=slope\end{array}$

Calculation:

Since , the graph is a straight line with a y -intercept of -1.

So, it matches the equation given in option A.

The equation is :

  $y=2x-1$
