Graph - Explain
y = 2x + 1
Explain how to graph this equation.
Start at origin. Move up 1 on the y-axis. For the slope move up 2 and 1 to the right.
(5, 7) and (3, 6)
What is 1/2?
Write an equation in slope-intercept form when slope = 3 and the y-intercept is 2
What is y = 3x + 2?
What is the slope and y-intercept?
4y=-2x+12
slope = -1/2
y-intercept = 3
y = -2/3x - 7
Explain how to graph this equation.
Start at the origin. Move down 7 on the y-axis. For the slope move down 2 and 3 to the right.
Write in slope-intercept form: slope = 1/4; y-intercept = -6
What is y = 1/4 x - 6?
What is the slope and y-intercept?
y = 5/3x + 5
slope = 5/3
y-intercept = 5
y = 6/7x - 5
Explain how to graph this equation.
Identify the slope: y = -5/2 x - 3/4
What is -5/2?
What is the slope and y-intercept?
-y = 1/2x+6
slope = -1/2
y-intercept = -6
4x + y = 8
Explain how to graph this equation.
Start at the origin. Move up 8 on the y-axis. For the slope move down 4 and 1 to the right.
Identify the y-intercept: y = 3/4 - 2
What is -2?
What is the slope and y-intercept?
-y = -5/2x+7
slope = 5/2
y-intercept = -7
2x + 4y = 12
Explain how to graph this equation.
Start at the origin. Move up 3 on the y-axis. For the slope move down 1 and 2 to the right.
What is the slope and y-intercept?
-x + y = -2
slope = 1 (1x)
y-intercept = -2
