# How to Write an Equation for Each Vertical Tangent to the Curve?

Most tangents to curves have equations that follow the format of "y = mx + c." In these equations, "m" represents the tangent's slope, and "c" represents its intersection with the y-axis. Vertical ...

## How to Write an Equation in Slope-Intercept Form for Each Line?

Linear equations can take several forms. The standard form is aX + bY = c, where a, b and c are numbers. The formula when you know two points, (X1, Y1) and (X2, Y2), is Y - Y1 = (Y1 - Y2)X / (X1 - ...
