Answer:
The linear function is
.
Explanation:
A linear function is given by the formula,
, where m is the slope and c is the y intercept of function.
The following two points lie on the graph; (0,-1) and (3,-10)
Inserting this two points we get,

,
solving this two equations we get,
m = -3 and c= -1
Thus, the linear function is given by,
