Question 937401: Find an expression for the function whose graph is the given curve. (Assume that the points are in the form (x, f(x)).)
The line segment joining the points
(1, −1), and (5, 13)
f(x)= ?

(1, -1), and
(5, 13) m =%28y%5B1%5D+-+y%5B2%5D%29%2F%28x%5B1%5D+-+x%5B2%5D+%29, m = -13/-4 = 13/4
***Using point-slope form, y+-+y%5B1%5D+=+highlight_green%28m%29%28x+-+x%5B1%5D%29
y+1 = (13/4)(x-1)
y = (13/4)x - 17/4
Standard Form:
13x - 4y = 17
