Answer

Hence, the correct graph is $D.$

Work Step by Step

The given linear equation is $\Rightarrow 5x-3y=30$ $x$ intercept. Substitute $0$ for $y$. $\Rightarrow 5x-3(0)=30$ Simplify. $\Rightarrow 5x=30$ Divide each side by $5$. $\Rightarrow \frac{5x}{5}=\frac{30}{5}$ Simplify. $\Rightarrow x=6$ The $x-$ intercept is $6$, so plot the point $A=(6,0)$ $y$ intercept. Substitute $0$ for $x$. $\Rightarrow 5(0)-3y=30$ Simplify. $\Rightarrow 0-3y=30$ $\Rightarrow -3y=30$ Divide each side by $-3$. $\Rightarrow \frac{-3y}{-3}=\frac{30}{-3}$ Simplify. $\Rightarrow y=-10$ The $y-$ intercept is $-10$, so plot the point $B=(0,-10)$ Draw a line through the points $A$ and $B$. Hence, the correct graph is $D.$
