If (y=(r+6)x+(r-3)) passes through the origin, what will be its slope?

Answer and explanation

Correct answer: 9

The line is in the form y = mx + c, where the slope m = r + 6 and the y-intercept c = r - 3. A line passing through the origin (0, 0) must have y-intercept 0. Hence, r - 3 = 0, so r = 3. Therefore, the slope is r + 6 = 3 + 6 = 9. Option 3 is the value of r, not the slope. Exam tip: For y = mx + c to pass through the origin, set c = 0 directly.
