Basic function of straight line is defined as y = mx + c where m is the gradient and c is the Y intercepts

Gradient is calculated when minimum of 2 coordinates are given by way of placing the difference of y’s over the difference of x’s

Example :  (x₁ , y₁) (x₂ , y₂)

y₁ – y₂ / x₁ – x₂ = gradient

What is c in the straight line equation of y = mx + c?

•   c  is the value of y on the Y axis where the line intersect with the Y axis

•   Coordinate (0, c) or Y intercepts

•   The distance on the point where the straight line intercept the Y axis from the point of origin
