Question 1 What is the gradient and the y-intercept for a straight line with the equation ???????? = 6???????? − 5? The given equation is y = 6x - 5, which is in slope-intercept form, where the slope is 6 and the y-intercept is -5. Therefore, the answer is [2] Slope = 6, y-intercept = - 5. [1] Slope = 6, y-intercept = 5 [2] Slope = 6, y-intercept = -5 [3] Slope = 5, y-intercept = -6 [4] Slope = 5, y-intercept = 6 Question 2 A straight line crosses the x-axis at (3, 0) and the y-axis at (0, 2). What is the y-intercept for this line? The line crosses the y-axis at (0, 2), which means the y-intercept is 2. Therefore, the answer is [4] y-intercept: 2. [1] y-intercept = 3 [2] y-intercept = 0 [3] y-intercept = 6 [4] y-intercept: 2 Question 3 Calculate the gradient of a straight line which passes through points (4, 9) and (8, 12)
