Firs solve the function for range of values of x
suppose f(x)=3x+10
then take the range from -3<=x<=3
now u get the values as:-
x--    -3   -2   -1    0    1    2    3
f(x)-   1     4    7   10   13  16   19

now make a Cartesian plane and plot the graph x against f(x)
keep the values of x on x-axis and those of f(x) on y-axis
also keep in mind the slope of the line or gradient in 3 and y intercept that is the point where line intercepts y-axis in 10 thus the equation is in the form of y=mx+c where m=3(gradient) and c=10(y-intercept) in the above equation

hope u get it ;)
