Work out the value of the change in the \(y\)-coordinate divided by the change in the \(x\)-coordinate. This gives 6 ÷ 2 which is 3. The gradient of the line is 3 Find the \(y\)-intercept of the ...

Watch this video to learn about the equation of a straight line. Since we are given 2 points that already lie on the line, using the formula as before, we need to calculate the gradient first.
