Question

1 Test whether the given point lies on the straight line (or curve) with the given equation.

A. (1,2) on y = 5x - 3

Answer 1

the point (1, 2 ) lies on the line

Explanation:

to determine if the point (1, 2 ) lies on the line, substitute the x- coordinate into the equation and if the value obtained is equal to the y- coordinate , then it lies on the line.

y = 5x - 3 ( substitute x = 1 )

y = 5(1) - 3 = 5 - 3 = 2 ← equals the y- coordinate

Then the point (1, 2 ) lies on the line
