Relationship b has a greater rate than relationship a. this graph represents relationship a.

which equations could represent relationship b?

select each correct answer.

y = 1.4x

y = 2.2x

y=1/2x

y = 3x

All of them except y=1.4x because rate is the same as slope and the slope of that graph is 2 so you pick each one that has a higher slope of 2.  

Hope this helped more than the other person who answered.  Good Luck!

Ithink it's the first one ( let me know if it right)
