# Chapter R - Elementary Algebra Review - R.3 Introduction to Graphing - R.3 Exercise Set: 34

$\left( 0,\dfrac{4}{3} \right)$

#### Work Step by Step

Substituting $x=0,$ then \begin{array}{l}\require{cancel} 3y+x=4 \\\\ 3y+0=4 \\\\ 3y=4 \\\\ y=\dfrac{4}{3} .\end{array} Hence, the coordinates of the $y$-intercept are $\left( 0,\dfrac{4}{3} \right) .$ Using the $y$-intercept, the graph of the given equation is shown above.
