Question 183511
Does the graph y=-x+3 pass through (2,1)

This is very easy. To find the graph pass through a coordination or not,we just put the number in the coordination in to the graph equation and see that the equation would be still right.

y = -x + 3
coordination (2,1)

1 = (-2)+3  This is right.

Then the graph y=-x+3 pass through (2,1)  Ans.
