Double-check your inputs to ensure accuracy.Ĭlick the "Calculate" button to find the equation of the line based on the provided inputs. Depending on the chosen type, enter the required inputs. You can opt for slope and point, or two points. Tailored for students, educators, engineers, and math enthusiasts, it helps to calculate line equations with no effort. If it decreases when moving from the upper left to lower right, then the gradient is negative.Introducing the Line Calculator, a tool for quickly and accurately finding line equations. If the graph of the line moves from lower left to upper right it is increasing and is therefore positive. The sign in front of the gradient provided by the slope calculator indicates whether the line is increasing, decreasing, constant or undefined. You can also use the distance calculator to compute which side of a triangle is the longest, which helps determine which sides must form a right angle if the triangle is right. The computations for this can be done by hand or by using the right triangle calculator. If any two sides of a triangle have slopes that multiply to equal -1, then the triangle is a right triangle. The slopes of lines are important in determining whether or not a triangle is a right triangle. This can be obtained using the midpoint calculator or by simply taking the average of each x-coordinates and the average of the y-coordinates to form a new coordinate. The midpoint is an important concept in geometry, particularly when inscribing a polygon inside another polygon with its vertices touching the midpoint of the sides of the larger polygon. Just as slope can be calculated using the endpoints of a segment, the midpoint can also be calculated. The article below is an excellent introduction to the fundamentals of this topic, and we insist that you give it a read. The slope of a line has many significant uses in geometry and calculus. Right away, the calculator tells us that y 2 = 10.92. To find the point where the line crosses the y-axis (i.e., x = 0), enter 12% in percent grade (9, 12) as the coordinate of the first point, and x 2 = 0. ![]() You can use this calculator in reverse and find a missing x or y coordinate! For example, consider the line that passes through the point (9, 12) and has a 12% slope. If we need the line's equation, we also have it now: y = 0.16667x + 4.83333. ![]() Instantly, we learn that the line's slope is 0.166667. Enter the x and y coordinates of the first point, followed by the x and y coordinates of the second one.
