Post an actual problem.

on a graph of a direct variation equation wat is the y intercept?

The general form for a direct variation is

y = k*x

where "k" is known as the constant of variation.

Compare this to the slope-intercept form of a linear equation:

y = m*x + b, where m is the slope and b is the y-intercept.

Does this help you determine the y-intercept for the graph of a direct variation equation?

If you're still confused, remember that any point on the y-axis has an x-coordinate of 0. So you can find the y-intercept by substituting 0 for x...........

Mrs?,

I am impressed - you know "wat" is what......
