Question

Is the point (-10, -34 ) on the line y=3x-4 Show how you know

Answer 1

yes

Explanation:

Substitute x = - 10 into the equation and if the value obtained equals - 34 then the point satisfies the equation and lies on the line

x = - 10 : y = (3 × - 10) - 4 = - 30 - 4 = - 34 ← agrees

Hence (- 10, - 34) lies on the line y = 3x - 4
