Question

If the point (1,a) lies on the line y = 3x - 5, what is the value of a?

Answer 1

a = - 2

Explanation:

Since the point (x, y) = (1, a) lies on the line, substituting this value of x = 1 should give the corresponding value of y which is a

y = 3x - 5

At (1, a)
a = 3(1) - 5

a = 3 - 5

a = - 2
