Question

Show that the point (1,5) lies on the line y = x +4

Answer 1

Answer:

Step-by-step explanation:

(x , y) = (1 , 5)

Now substitute into the eqn.

y = x + 1

5 = 4 + 1

=> This is correct

=> Therefore, it is on the line

Answer 2

Answer:

5 = 1+4

5 = 5

Step-by-step explanation:

(1,5) is an ordered pair composed of x and y values:

x = 1

y = 5

- Simply, substitute them into the equation in the place of x and y:

y = x +4

5 = 1+4

5 = 5

- both sides are equal, so this point lies on the correct line.
