Answer:

Graph is option A

Step-by-step explanation:

3x + 5y = –15

To graph the equation , we need to get y alone

[tex]3x + 5y = –15[/tex]

Subtract 3x on both sides

[tex]5y = -3x–15[/tex]

Divide whole equation by 5

[tex]y=-\frac{3x}{5} -3[/tex]

To graph this equation , we need to make a table

Plug in some number for x  and find out y

x                [tex]y=-\frac{3x}{5} -3[/tex]

0                -3

-5                0

Two points on the graph is (-5,0)  and (0,-3)

Graph is option A
