Web11 mrt. 2024 · The equation for a line is, in general, y=mx+c. To find the equations for lines, you need to find m and c. m is the slope. For example, if your line goes up two units in the y direction, for every three units across in the x direction, then m=2/3. If you have the slope, m, then all you need now is c. WebThe equation y = mx + c is the general equation of any straight line where m is the gradient of the line (how steep the line is) and c is the y -intercept (the point in which the line crosses the y -axis). y = mx + c is a linear equation and the variables x and y relate to coordinates on the line. tattoos in weird places on womenWebIf a line, y—mx+ c is a tangent to the circle, (x—3)2 + y2 = 1 and it is perpendicular to a line L1, where L1 is the tangent to the circle, x2 + y2 = 1 at the point ( 21, 21); then : 1549 72 JEE Main JEE Main 2024 Conic Sections Report Error A c2 +7c+ 6 = 0 B c2 −6c+ 7 = 0 C c2 −7c+ 6 = 0 D c2 +6c+ 7 = 0 Solution: tattoos in worcester ma

"WebThe tangent to a circle equation x 2 + y 2 = a 2 for a line y = mx +c is given by the equation y = mx ± a √ [1+ m 2 ]. The tangent to a circle equation x 2 + y 2 = a 2 at (a 1, b 1) is xa 1 +yb 1 = a 2. Thus, the equation of the tangent can be given as xa 1 + yb 1 = a 2, where (a 1, b 1) are the coordinates from which the tangent is drawn. " - If a line y mx+c is a tangent to the circle
