To calculate: To graph the equation

Answer to Problem 18MCQ

Graph of equation is sketched

Explanation of Solution

Given information:Equation is $y=x+2$

Formula Used:

Ordered Pair: An ordered pair is a composition of the x-coordinate and the y-coordinate and is written as $\left(x,y\right)$

Calculation:

Equation is given as follows:

  $y=x+2$

In order to find the solutions of above equation:

When $x=0$

  $\begin{array}{l}y=0+2\\ y=2\end{array}$

When $x=1$

  $\begin{array}{l}y=1+2\\ y=3\end{array}$

When $x=2$

  $\begin{array}{l}y=2+2\\ y=4\end{array}$

Thus, solutions of equation in ordered pair are $\left(0,2\right),\left(1,3\right),\left(2,4\right)$

Plotting the points to graph the equation:

  

Conclusion:

Hence, graph of equation is sketched.
