Try this
Adjust the sliders on the right. They control the slope (m) and the intercept (b) of the line.
The equation and the line will change accordingly. You can also drag the origin.

is the intercept (where the line crosses the y-axis)

Recall that the slope (m) is the "steepness" of the line and b is the intercept - the point where the line crosses the y-axis.
In the figure above, adjust both m and b with the sliders to see the effect of these variables.

Equations of this type that have no exponents in them (such as x^{2}) are called 'linear equations' because they always graph as straight lines. The word "linear" is derived from "line".

thanks but I wanted to know about the equation im pretty Shure it is a parabola because it has x= for the directrix and it opens left right so my question was what is my H,K
