Question

mathteacher1729 · Answer

This is easy.  

Let x = 0 and solve for y. 

Or let y = 0 and solve for x. :)

It's not too hard. 


 -7x - 14y = -98 
-7(0) - 14y = -98            let x = 0 
       0 -14y = -98                   
           -14y = 98     
                 y = 98/(-14)   divide by -14 
                 y = -7             simplify

One ordered pair is (0,-7)

Can you find the ordered pair if you let y = 0 first?
