Determine, in slope intercept form, the equation of the line which has slope of eight and a ๐‘ฆ-intercept of negative four.

What is slope intercept form? Slope intercept form is ๐‘ฆ equals ๐‘š๐‘ฅ plus b. In this form, ๐‘š equals the slope and ๐‘ equals the ๐‘ฆ-intercept.

We know that our line has a slope of eight and a ๐‘ฆ-intercept of negative four. So we plug in what we know. Our slope equals eight and our ๐‘ฆ-intercept equals negative four. We can simplify that equation to say ๐‘ฆ equals eight ๐‘ฅ minus four.
