What is thelinear function whose graph has the points (-4,0) and (1,3)?

The linear function whose graph passes through (-4 , 0)
and (1, 3) is the equation of the line passing through the two
points.

The equation of the line passing through (x1 , y1)
and (x2, y2) is given by (y - y1) = [(y2 - y1)/(x - x2)]*(x -
x1).

Substituting the values given to us we
get:

(y - 0) = [( 3- 0)/(1+ 4)]*( x +
4)

=> y = (3/5)*(x +
4)

Therefore the function
is

f(x) = (3x/5) +
12/5
