At which point does the line y = 2x + 3 meet the x-axis?
Answer and explanation
Correct answer: B. (-3/2, 0)
- Step 1: On the x-axis y = 0, so 2x + 3 = 0. Step 2. x = -3/2, giving the point (-3/2, 0). Answer: (-3/2, 0). Why not the others: (3/2, 0): The sign is wrong: 2x = -3 gives a negative x. (0, 3): That is where the line meets the y-axis. (-3, 0): That forgets to divide by the gradient 2.
