Answer 1

Explanation : 1 Mark
Calculation : 1 Mark
Result : 1 Mark

If the two points lie on the line y = 3 + 2x, their cordinates should satisfy the linear equation.

Substituting(1, 5) in y = 3 + 2x we get

5 = 3 + 2

5 = 5

Therefore, (1, 5) lies on the line y = 3 + 2x

Substituting (0, 3) in y = 3 + 2x we get

3 = 3 + 2 x 0

3 = 3

Therefore, (0, 3) lies on the line y = 3 + 2x
