Answer

$$(2,0), \quad (0,4), \quad (-3,-5 ).$$

Work Step by Step

Substitute the value of $x$ and solve for $ y $ to get the ordered pair $ (x,y)$ as follows: $$ y= 3(2) + 4 \Longrightarrow y=6+4 \Longrightarrow y =0 ,$$ $$ y= 3(0) + 4 \Longrightarrow y=0+4 \Longrightarrow y =4 ,$$ $$ y= 3(-3) + 4 \Longrightarrow y=-9+4 \Longrightarrow y =-5 ,$$ Hence, we have the pairs $$(2,0), \quad (0,4), \quad (-3,-5 ).$$
