GCSE Maths Practice: graphs-of-linear-functions

Question 5 of 10

This question asks which line passes through two given points.

‹ ›

\( \text{Which of these lines passes through both } (0, 0) \text{ and } (2, 4)? \)

Select all correct options:

\( y = 2x \) \( y = x \) \( y = x + 1 \) \( y = 4x \)

Calculate the gradient and substitute a point to find the correct equation.

Gradient = change in y / change in x. y-intercept is where x = 0.
