Answer:
B
Step-by-step explanation:
First calculate the slope. [tex]\frac{y2-y1}{x2-x1}[/tex]. In this case, the slope is [tex]\frac{4}{5}[/tex].
If you look at all of the answer choices, they are in slope - intercept form. This makes it easier! All you have to do is find an equation with the slope 4/5 that uses the point (4,1) or (9,5).
The standard slope intercept form for a point (a,b) is
y-b = m(x-a).
Remember that two negatives equal a positive.
Substitute in the slope for m and (4,1) or (9,5) for the point (a,b).
