Question 773369
a straight line equation is y = mx + c
where (x,y) is a point that lies on the line.
c is a constant
and m is slope
According to your question
(x,y)=(-5,1)
m= 1/5
substituting them into the equation , we get
1=-5*1/5 +c
=>c=2
linear equation would be
y=x/5+2
point satisfying this could be 
for x=10 y=4
for x=5  y=3
for x=0 y=2 and so on..

now we put this linear equation in terms of graph
first drawing x-axis and y-axis on graph paper and 
just by marking the points and then connect those points.
