Web4 Oct 2024 · Question 2. Show that lines represented by x 2 + 6xy + gy 2 = 0 are coincident. Question is modified. Show that lines represented by x 2 + 6xy + 9y 2 = 0 are coincident. Solution: Comparing the equation x 2 + 6xy + 9y 2 = 0 with ax 2 + 2hxy + by 2 = 0, we get, a = 1, 2h = 6, i.e. h = 3 and b = 9 WebAn x-intercept is a distance at which the line cuts the x-axis. Suppose a line l with slope m intersects the y-axis at a distance ‘c’ from the origin. The equation of line l passing through the point (0, c) is given by: m = (y − c) / (x − 0) or, y = mx + c. Consider a line l with slope m intersects the x-axis at a distance ‘d’ from ...

WebLook at the National 4 straight line section before continuing. We can find the equation of a straight line when given the gradient and a point on the line by using the formula : \[y - b = m(x - a)\] Web5 Apr 2024 · Question 14. Find equation of the line through the point (0, 2) making an angle 2π/3 with the positive x-axis. Also, find the equation of line parallel to it and crossing the y-axis at a distance of 2 units below the origin. Solution: Given that. Point (0, 2) and θ = 2π/3. slope (m)= tan θ. m = tan (2π/3) = -√3. bovey castle golf breaks
