Question

Does the line 3y+x=5 pass thru the point (2,7)?

Answer 1

plug the point in and see

(2 , 7)
(x , y)

you have an x....you have a y

you have an equation that has both an x and y so

3y + x = 5

plug them in

Answer 2

23=5?

exactly....is that true?

definitely not...so that point does not fall on this line
