WebAccording to the definition of y-intercept, the y-intercept of a graph is the point where it cuts (or) intersects the y-axis. We know that on the y-axis the x-coordinate is 0. Hence the … WebNov 4, 2016 · When a graph of any form of equation intersect the x-axis, this automatically means that y = 0. And then we solve for x to find the coordinates of the point of intersection, or just the value of x. y = -3x - 18 -3x - 18 = 0 We add 18 in both sides so we can get the variables on a side and the numbers on the other: -3x - 18 + 18 = 0 + 18 -3x = 18

WebThe y-intercept is the point at which the graph crosses the y-axis. To find the x-intercept of a line, substitute 0 for y into the equation and solve for x. ... Two lines in a plane are perpendicular if they intersect to form a right angle. The slope can be used to determine whether two different lines are parallel or perpendicular. buy sell non repaint

WebJun 1, 2015 · y = m x + b denotes the y-coordinate at x = 0, hence, the y-intercept is given b, meaning the point of intersection of the line and the y-axis is the point ( 0, b). In your example, y = 3 x + 4, slope = m = 3, and b = 4 is the y-value at which the line "intercepts" the y-axis (y axis: x = 0 ). Hence ( 0, 4) is the point of intersection. Share Cite WebOct 19, 2010 · A Cartesian coordinate system, or rectangular coordinate system, is a 2-dimensional coordinate system. The X-axis and Y-axis only intersect at one special point called the origin. This point has the coordinates of … WebApr 2, 2024 · The point where the function's graph contacts or crosses the y-axis is known as the y-intercept. By putting x = 0 to the function, the y-intercept may be obtained since its x-coordinate is always 0. Y Intercept Formula The equation of the line, which intersects the y-axis at a point is given by: y = mx + c cerebellum anterior view
