SECTION 4.4
Slope refers to the _______________ of the line and whether it goes _______________ or _______________. If
the line goes _______________ from left to right, we say that the line has a _______________ slope. If the line
does _______________ from the left to right, we say that the line has a _______________ slope.
What is the slope of a HORIZONTAL line? Why?
What is the slope of a VERTICAL line? Why?
Write down the slope formula below:
SLOPE = m = _______________ = ____________________ = Δ y = ___________________
Δx
Do an example from the video on “how to find the slope from two points.”
Graph the point with the slope.
(0, 3) m =
Which direction should the line point?
What is SLOPE-INTERCEPT FORM? Why is it so useful in graphing lines?
Graph the line in slope-intercept form.
y = 3x – 4
Which direction should the line point?
Graph the line.
3x + 2y = -6
Which direction should the line point?
