This math topic focuses on finding the x-intercept of linear equations given in slope-intercept form (y = mx + b) where the intercepts involve decimals. Each problem presents a different linear equation and multiple-choice answers. The x-intercept is the point where the graph of the equation crosses the x-axis, corresponding to setting y = 0 and solving for x. This requires manipulating the equation algebraically to isolate and calculate x, particularly when coefficients and constants are given as decimals. This skill is essential for understanding the behavior of linear functions on a graph and is fundamental in algebra studies.
