Question

How do you graph using the intercepts for `-x+3y=-5`?

Answer 1

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]}
