Slope

May 16, 2008

Do Now:
Read todays goal.
Find the slope of a line that passes through (1,3) and (2, 6)

Today's Goal:
To learn more Slope and lines passing through the slope.

Lesson:
Formulas:
Equation of a line y = mx + b
Slope of line m = rise/run = (y2 - y1)/(x2 - x1)
1) Find the equation of the line passing through A(-4,3), B(2, -1)
Steps
a) Find the slope using the slope of a line formula.
b) Graph the points and draw a line that passes through the points.
c) Find the point that passes through the y axis - identify that as b - the y- interecept.
d) Using b and m, write the equation of the line.
