It is known that the intersection point of the image and the Y-axis of the linear function y = (3a-7) x + A-2 of X is above the x-axis

Original problem: it is known that the intersection point of the image and the Y-axis of the linear function y = (3a-7) x + A-2 of X is above the x-axis, and Y decreases with the increase of X
Let x = 0
y=a-2
According to the meaning of the title
a-2>0
a>2
Because y decreases with the increase of X
therefore
3a-7
