WebApr 11, 2024 · For example, if the slope of a line is 2 and its y-intercept is 4, the equation of the line in slope-intercept form would be: y = 2x + 4. Here, the y-intercept is 4, which means that the line intersects the y-axis at the point (0, 4). The Y-intercept of a straight line: The y-intercept of a straight line is the point where the line intersects ... Webmx = y – c. Adding the variable ‘c’ on both sides, we get. y = mx + c. The slope-intercept formula of a straight line is derived hereby. Since, this basic equation of a straight line includes the factors like slope (m) and y-intercept (c), therefore, it is called the slope-intercept form of a straight line.
WebSep 24, 2024 · The y-intercept of a line is the place where a line crosses the y-axis. That means it's the place where x = 0. In both cases, there's a simple way to figure out the intercepts.
