Question

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

Answer 1

5 = 1+4

5 = 5

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.

- I hope this helps :)
