Graphing a Linear Equation Given in Any Form

What is the first step in solving a system by graphing?

• Write both linear equations in slope-intercept form

• Get x by itself

• Compare the slopes of both equations

• Write both equations in standard form

What is the solution to the system?

• (0, 3)

• (1, -1)

• (-3, 1)

• (1, 3)

What is the
slope-intercept form
of the equation
-8x+2y=4

• none

• y=2-4x

• y=4x+2

• y=4x-8y

Write in slope intercept form
5x - 3y = -9

• y = (5/3)x - 3

• y = (5/3)x + 9

• y = (5/3)x + 3

• y = (3/5)x + 3

y = 2x + 5

• y = 2x + 5

• y = -2x - 5

• y = -2x + 5

• y = 5x - 2

y = 2x + 5

• y = 2x + 5

• y = -2x - 5

• y = -2x + 5

• y = 5x - 2

Write the equation in slope-intercept form:
-3y + 5x = 12

• y = -4 + 5x

• y = -4 + 5/3x

• y = 4 - 5/3x

• y = 12 + 5x

What is the solution?

• (1, -1)

• (-1, 1)

• (0, -2)

• (2, 0)

What are the steps for graphing a line?

• Plot y-intercept
  count slope ratio plot second point
  Draw the line.

• Make a table
  Plot slope
  Draw line

• Plot two points
  Check slope
  Draw line

• Draw line
  Hope it is right

What is the solution?

• (2, 2)

• (3, 2)

• (3, 4)

• (2, 3)
