Point-Slope Lesson 2.2
The slope gives you the direction of the line and the 
steepness of the line.
Point-Slope Form
y - y1 = m(x - x1)
(x1, y1) is the point given, but be careful!The coordinates are the opposite of whatyou see!
This is the
slope
    In the point-slope form
        y - y1 = m(x - x1),
what does the "m" stand for?
In the point-slope form,
    y - y1 = m(x - x1),
what is the given point?
(x, y)
(-x, -y)
(-x1, -y1)
(x1, y1)
What is the x coordinate if the expression 
is x - 5?
What is the y-coordinate if the expression
is y + 2?
Leave your answer in this format:  (x, y)
What is the given point in
     y - 3 = 4(x - 1)?
Just type the #
What is the slope in
  y + 4 = -2(x - 9)?
Leave your answer in this format:  (x, y)
What is the point given in
     y - 2 = 6(x + 5)?
Write the equation in point-slope form
for a line that passes through (3,-2) and
has a slope of 1/3.
y + 2 = 1/3(x - 3)
y - 2 = 1/3 (x - 3)
y - 3 = 1/3 (x + 2)
y + 3 = 1/3(x - 2)
What is the point given in this equation?
(3, -8)
(-3, 8)
 (-8, 3)
(8, -3)
y - 3 = 4(x + 8)
What is the slope of
  y - 1 = -(x + 3)?
Just type the #
Which is the correct slope-intercept form of 
y - 3 = 2(x + 4)?
y = 2x + 8
y = 2x + 11
y = 2x + 5
y = 2x - 1
Which is the correct slope-intercept form of
y + 4 = 1/2(x+ 6)?
y = 1/2x + 10
y = 1/2x + 7
y = 1/2x + 2
y = 1/2x - 1
Change this equation into slope-intercept form.
y + 5 = -3(x - 3)
y = mx + b
Find the slope using these two points:
m = 
(4, -1) and (6, -5)
Find the slope between these two points:
1/3
-1/3
3
-3
(-2, 6) and (4, 8)
Which equation(s) does/do not represent a line that passesthrough (4, -2) and (-6, 3)?
 y - 2 = -1/2(x + 4)
y + 2 = -1/2(x - 4)
y - 3 = -1/2(x + 6)
y + 6 = -1/2(x - 3)
Which equation represents the line that passes
through (4, -2) and has a slope of 5?
y + 2 = 5(x + 4)
y - 2 = 5(x - 4)
y - 4 = 5(x + 2)
y + 2 = 5(x - 4)
Which line represents 
y - 2 = 3(x - 4)?
