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
