ok ssooooooo! how i set up equaztion.

mathstudent55 · Answer

Let's say a horizontal goes through (0,6), which is 6 on the y-axis. Every point of this line has a y-value of 6. It makes no difference what the x-value is. The equation is simply, y = 6.

mathstudent55 · Answer

If the line in your case goes through (2,4) and is horizontal, it also goes through (0,4), or 4 on the y-axis, so its equation is y = ____
Can you fill that in?
