Chapter 11.1, Problem 1QR

To determine

To Find:The equation relating $x$ and $y$ .

Answer to Problem 1QR

Therequired answer is $y=2x+1$ .

Explanation of Solution

Given:

  $x=t+1$  ........ (1)

  $y=2t+3$  ........ (2)

Calculation:

From equation (1)

  $\begin{array}{l}x=t+1\\ t=x-1\end{array}$

From equation (2)

  $y=2t+3$

Substitute $x-1$ for $t$ in equation (2)

  $\begin{array}{l}y=2\left(x-1\right)+3\\ y=2x-2+3\\ y=2x+1\end{array}$

Conclusion:

Hence, the required answer is $y=2x+1$ .
