graph{(-5+x)/3 [-10, 10, -5, 5]}

Explanation:

We can draw a straight line between the x intercept (when y=0) and the y intercept (when x=0)

x intercept: #-x+3(0)=-5# so #-x=-5# so #x=5#

So this gives you one co-ordinate (5,0)

y-intercept #-(0)+3y=-5# so #y=-5/3#

So this gives another set of co-ordinates #(0,-5/3)#

So we sketch a line between these two points graph{(-5+x)/3 [-2.41, 7.654, -2.766, 2.266]}
