To find the x-intercept, set y = 0 in y = mx + c. This yields 0 = mx + c, which solves to x = −c/m, provided m ≠ 0.

Class 9 Ganita Manjari Part 2 Chapter 13 Page 121 Question Answer
The x-intercept is the point where a straight line crosses the horizontal x-axis, where the y-coordinate is always zero. Setting y = 0 in the slope-intercept equation y = mx + c gives 0 = mx + c. Subtracting c and dividing by the non-zero slope m yields x = −c/m. Thus, the formula for the x-intercept is −c/m.
