Answer:

Explanation:
your question is incomplete. you have not written the value of the slope.
How ever i can give you a methodology of the question by simply letting slop =4
General formula for equation of line is
y - y1 = m ( x- x1 ) ;
where (x1,y1) is know point in our case its (3,8)
m is the slop in our case m=4, (x,y) is the general point of the required line
so our equation become
y-8=4(x-3)
y= 4(x-3)+8
