Do: Write an equation of a line given the slope and a point.
Essential Question: How can you write the equation of a line when
given the slope and a point on the line?
Questions:
Use point-slope form to write the equation of a line passing through given point
and having given slope.
1) Write in point-slope form the equation of the line that passes
through the point (2, 3) with slope 4.
2) Write in point-slope form the equation of the line that passes
through the point (1, -2) with slope -3.
Questions:
3) Write in point-slope form the equation of the line that passes
through the point (-3, 5) with slope -2.
4) Write in point-slope form the equation of the line that passes
through the point (4, 2) with slope .
B) Writing an Equation Using Two Points
5) Write in slope-intercept form an equation of the line that passes
through points (-3, 0) and (6, 3).
6) Write in slope-intercept form an equation of the line that passes
through points (1, -1) and (2, 1).
Questions:
7) Write in slope-intercept form an equation of the line that passes
through points (0, -2) and (2, -5).
8) Write in slope-intercept form an equation of the line that passes
through points (0, 0) and (4, 1).
Questions:
C) Real-Life Application
9) You are pulling down your kite at a rate of 2 feet per second.
After 3 seconds, your kite is 54 feet above you.
a) Write an equation that represents the height y (in
feet) of the kite above you after x seconds.
b) Graph the equation.
c) At what height was your kite before you began
pulling it down?
d) How long will it take you to pull the kite all the way
down?
