Question

(1,5) (0,3) lie on the line y = 3+2x or not

Answer 1

Answer:

yes

Step-by-step explanation:

To determine if the points lie on the line, substitute the x- coordinate into the equation and if the value agrees with the value of the y- coordinate then the point lies on the line.

(1, 5 )

y = 3 + (2 × 1) = 3 + 2 = 5 ← true

(0, 3 )

y = 3 + (2 × 0 ) = 3 + 0 = 3 ← true

Hence the 2 points lie on the line with equation y = 3 + 2x
