anonymous · Answer

so the equations are 
g(x)=3x -4 
h(x)= -3x + 7
and j(x)=3x + 4 
all in order.

they all have the same slope except h(x) is flipped. because it's negative it's going from top left down to right bottom. the other two are positive slopes so its from bottom left to top right.  j(x) has a y intercept of 4 and it starts in the middle between g(x) and h(x). h(x) has the highest y intercept and g(x) has the lowest
