write an equation for the line in point slope form...when it passes through (9,1) and the x intercept is 5 and then slope intercept form...im so confused

You have two points identified; (5,0) and (9,1).
The slope of the line passing through these two points is m = (y1y2)/(x1x2) or m = (10)/(94) = 1/4.
Knowing the coordinates of point 1, (9,11), from y = mx + b, 1 = 9/4 + b making b = 5/4.
The line is therefore defined by y = x/4  5/4.
Checking:
for x = 5, y = 5/4  5/4 = 0.
for x = 9, y = 9/4  5/4 = 4/4 = 1.
