Best Answer

Since there are no powers of x or y or trigonometric functions or anything like that, you know that the graph is a straight line. So two points on the line is all that you need.

Step 1:

Let x = 0

and find y from the equation: y = -0 + 3 = 3

so one point on the graph (the y-intercept) is (0, 3)

Step 2:

Let x = 5 (or any other number)

and find y from the equation: y = -5 + 3 = -2

so another point on the graph is (5, -2)

Step 3:

Join the two points.

Done!

If x equals 3 then graph the function x equals -3x plus 3?

First of all, if 'x' is 3, then 'x' doesn't equal -3x+3 . You must mean y = -3x + 3.If x=3, then (-3x + 3) = -6 .The graph is the point (3, -6) .
