Question

Does the point (2,5) lie on the line y=3x-1?

Answer 1

Well let’s sub in the values: is 5 = 3*2-1? It is and therefore the point does lie on the line

Answer 2

Answer:

yes

Step-by-step explanation:

To determine if (2, 5) lies on the line, substitute x = 2 into the right side of the equation and if the value obtained equals y = 5, then it lies on the line.

3(2) - 1 = 6 - 1 = 5 ← equals the y- coordinate of the given point

Thus (2, 5 ) lies on the line y = 3x - 1
