IA4-3 Graphing from an Equation

Objective:

Students will graph lines using only the slope and y-intercept of a linear equation.

If you need more review of the parts of an equation, watch the video below. I suggest you take some notes as well.

1

For the equation y=2x-4, where would you plot the y-intercept?

(0,4)

(0,-4)

(4,0)

(-4,0)

1

For the equation y=2x-4, after you plot the y-intercept, where will you go to plot your next point?

up 1, right 2

down 1, right 2

up 2, right 1

down 2, right 1

To see the explanation of the previous equation, watch the video below.

For the equation y=2x+6, where would you plot the y-intercept?

(0,2)

(0,6)

(2,0)

(6,0)

For the equation y=2x+6, once you plot the y-intercept, where would your next point be?

up 2, right 1

up 1, right 2

down 1, right 2

down 2, right 1

1

For the equation
Where would you plot the y-intercept

1

For the equation
Once you plot the y-intercept, where would you go next?

up 1 and right 3

up 1 and right 5

up 5 and right 1

up 3 and right 1

1

For the equation
Where would you plot the first point (the y-intercept)?

(-2,3)

(-2/3, 0)

(0,6)

(6,0)

1

For the equation
Where would you plot the second point from the y-intercept?

up 2, right 3

up 3, right 2

down 3, right 2

down 2, right 3

To see the previous equation graphed, watched the video below.

1

If an equation has a slope of -4, for example y=-4x+2, we would make our first point at the y-intercept (0,2) and then go

up 4, right 1

down 4, right 1

up 1, right 4

down 1, right 4

1

To graph the equation
you would...

start at (5,0) and go up 3, then right 1

start at (0,5) and go up 3, then right 1

start at (3,0) and go up 5, then right 1

start at (0,3) and go up 5, then right 1

1

To graph the equation
You would

Start at (1,0) and go down 4, then right 1

Start at (0,1), and go down 4, then right 1

Start at (-4,0) and go up 1, then right 1

Start at (0,-4) and go up 1, then right 1

1

To graph the equation
What is the first point you would graph? Type (x,y) with parentheses and no spaces.

1

To graph the equation
Once you graph the y-intercept, where do you go from there? You can use the graph to plot the first two points, and type the coordinates of the 2nd point. You can also specify direction and distance "up 5 right 10" for example.
