Line 1 : y = 3x -2. Equation of a line general formula : y = mx + c , where m = gradient. Therefore, for y = 3x - 2, m = 3 and therefore the gradient = 3. Line 2 : 3y - 9...

There are a few different ways to approach this problem but the simplest and most easy to visualise solution comes from sketching the curve y = x² + 5x - 24 and identifying the range of x-value...
