FAQs on Examples : Equation of a line : Part 2 Video Lecture - Mathematics (Maths) Class 12 - JEE

1. What is the slope-intercept form of the equation of a line?
Ans. The slope-intercept form of the equation of a line is y = mx + b, where m represents the slope of the line and b represents the y-intercept.
2. How can I find the equation of a line given two points on the line?
Ans. To find the equation of a line given two points (x1, y1) and (x2, y2) on the line, you can use the point-slope form of the equation: y - y1 = (y2 - y1) / (x2 - x1) * (x - x1). Simplify this equation to obtain the slope-intercept form if needed.
3. Can the equation of a line have a negative slope?
Ans. Yes, the equation of a line can have a negative slope. A negative slope indicates that the line is sloping downwards from left to right.
4. What does the y-intercept represent in the equation of a line?
Ans. The y-intercept in the equation of a line represents the point where the line intersects the y-axis. It is the value of y when x is 0.
5. How can I determine the slope of a line if I only know its equation?
Ans. If you have the equation of a line in slope-intercept form, y = mx + b, the slope (m) is the coefficient of x. For example, in the equation y = 2x + 3, the slope is 2.
