Question 125294
y=9x+7 is parallel to y=9x-2 


y = 9x +7  
"Slope : 9x"  
y- intercept : 7 
               

y=9x-2 
"Slope: 9x "
y-intercept : -2   
            

The reason  y=9x+7 is parallel to y=9x-2 because they have the same slope. Notice that I put the slope of each equation in quotation mark. Just remember, two or more line will always end up parallel if they have the same slope!

Hope that helps
