## FAQs on Examples (NCERT) - Straight Lines Video Lecture - Mathematics for Airmen Group X - Airforce X Y / Indian Navy SSR

 1. What is the equation of a straight line in the slope-intercept form?
Ans. The equation of a straight line in the slope-intercept form is given by y = mx + c, where m is the slope of the line and c is the y-intercept.
 2. How do you find the slope of a line when given two points on the line?
Ans. To find the slope of a line when given two points (x1, y1) and (x2, y2), we use the formula m = (y2 - y1)/(x2 - x1), where m represents the slope.
 3. What is the point-slope form of a straight line equation?
Ans. The point-slope form of a straight line equation is given by y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope of the line.
 4. How do you determine if two lines are parallel or perpendicular?
Ans. Two lines are parallel if their slopes are equal. Two lines are perpendicular if the product of their slopes is -1.
 5. Can a straight line have a negative slope?
Ans. Yes, a straight line can have a negative slope. The slope of a line represents the steepness or inclination of the line. If the line is sloping downwards from left to right, it has a negative slope.
