How do you work out the y intercept of a line
Did you know?
Web10 mei 2024 · The y-intercept of a line is the value of y where the line crosses the y-axis. In other words, it is the value of y when the value of x is equal to 0. Sometimes this has true meaning for the model that the line provides, but other times it is meaningless. We will encounter examples of both types in this section. WebTo find the intersection of two straight lines: First we need the equations of the two lines. If you do not have the equations, see Equation of a line - slope/intercept form and Equation of a line - point/slope form (If one of the lines is vertical, see the section below). Then, since at the point of intersection, the two equations will have the same values of x and y, we …
WebThe equation of a straight line is usually written this way: y = mx + b (or "y = mx + c" in the UK see below) What does it stand for? y = how far up x = how far along m = Slope or … WebStandard form: y = ax 2 + bx + c; Vertex Form: y = a (x - h) 2 + k; Intercept Form: y = a (x - p)(x - q) In each of the cases, the parabola opens up if a > 0, and it opens down if a < 0. Left/Right Opened Parabolas: The equation of a left/right opened parabola can be in one of the following three forms: Standard form: x = ay 2 + by + c
