A line extending on both sides till infinity without any no curves is called a straight line. It is an object in geometry which is characterized by zero width object and extends in opposite directions without any ends. A straight line was the first topic to be explained by Euclid- a founder of Geometry.
The equation of straight lines can be expressed in the form:
y = mx + b
Where y is the intercept
x is how far along
m is the slope or the gradient.
b is the intercept of y.
The line y = 3x + 5 has
Slope m=3 and y-intercept b = 5.
