Write the equation for the horizontal line passing through (4, -6).

Question

kewlgeek555 · Answer

So, first off you should know what the slope-intercept formula is.  Then, you should know what slope a horizontal line has, and afterwards, you solve to see the y-intercept.

So, do you know the slope-intercept formula?

no

Okay then.  The slope-intercept formula is...$$y=mx+b$$This is where y is the y-value, m is the slope, x is the x-value, and b is the y-intercept.

anonymous · Answer

y=mx+b

So, a horizontal line ALWAYS has a slope of zero.  That's why it's a 0-slope.  That gives you what to input for "m".  So, if you have a line that has zero slope, it's just a horizontal line, which number do you think is the y-intercept?  

HINT:  A horizontal line always has the same y-value.
