Answer:
Graph is option A
Step-by-step explanation:
3x + 5y = –15
To graph the equation , we need to get y alone

Subtract 3x on both sides

Divide whole equation by 5

To graph this equation , we need to make a table
Plug in some number for x and find out y
x 
0 -3
-5 0
Two points on the graph is (-5,0) and (0,-3)
Graph is option A
Can you please help me solve something
27.
Volume = length*width*height
So 3*3*3=27
There are infinitely many.
x+5=0
x^2-25=0
x^2+2x-15=0
again there are infinitely many
