Transcript of Objective To be able to recognize Horizontal and Vertical lines on the coordinate plane.
Objective•To be able to recognize Horizontal and Vertical lines on the coordinate plane.
Plot the points(3,-3), (3,-2), (3,-1), (3,0),(3,1), (3,2), (3,3)
What do you notice about
all the x values that
were plotted?
The Equation of the line is x = 3
Now you Plot the points (1,-3), (1,-2), (1,-1), (1,0),(1,1), (1,2), (1,3)
What is the
equation of the line?
The Equation of the line is x = 1
What did you notice about all the x values?
•When the x values are the same, what does the equation begin with?
Plot the points(-2,2), (0,2), (3,2)
What is the equation of the line?
Now you Plot the points(-2,5), (0,5), (3,5)
What is the equation of the line?
What did you notice about all the y values ?
•When the y values are the same, what does the equation begin with?
Graph the lines x = 4 & y = -2
What is the intersection pt. of the 2 lines?
(4,-2)
Write equations for the horizontal line and the vertical line that pass through the point
(-1, 4)
•x = -1
•y = 4
x = -1 & y = 4
Graph x = -2
(-2,4)
(-2,-3)
Graph x = -1
Graph y = 2
Graph y = 4
Write equations for the horizontal line and the vertical line that pass through the point (-1, 4) and then plot both lines
•x = -1
•y = 4
x = -1 & y = 4
The intersection is at (-1,4)
Write the equations of the line
•1.) (3,5), (3,-1), (3,0), (3,-2)
•2.) (5,5), (5,-1), (5,0), (5,-2)
•3.) (3,5), (-1,5), (0,5), (1,5)• 4.) (3,-2), (-1,-2),(0,-2),(1,-2)
Write the equations of the line
•1.) (3,5), (3,-1), (3,0), (3,-2)
•2.) (5,5), (5,-1), (5,0), (5,-2)
Write the equations of the line
•3.) (3,5), (-1,5), (0,5), (1,5)
• 4.) (3,-2), (-1,-2),(0,-2),(1,-2)
Write the Equation of the linePasses thru the point 4 on the x-axis
Write the Equation of the linePasses thru the point -2 on the x-axis
Write the Equation of the line
Passes thru the point 2 on the
y-axis
Write the Equation of the linePasses thru the point -5 on the
y-axis
Properties of y=k•Horizontal line
•Parallel to x axis
• Slope is zero
•Examples: y=4, y=-2, y=1
Properties of x=h•vertical line
•Parallel to y axis
• Slope is undefined
•Examples: x=4, x=-2, x=1
