Quiz 3 Review - Writing Linear Equations

Write the equation of the line graphed below.

Write the equation of the line graphed below.

Write a linear equation in the form of y=mx+b

• y= 3x + 5

• y = 5x - 3

• y = 2x + 3

• y = 5x + 3

Write a linear equation in the form of y=mx+b

• y = x + 2

• y = 2x - 1

• y = 3x - 2

• y = 2x +1

Write a linear equation in the form of y=mx+b

• y = -2x + 7

• y = 7x - 2

• y = x + 7

• y = -2x

Jenny writes the equation y = 1/2x +5.
Why is she incorrect?

• The slope is -2, the equation should be
  y = -2x + 5
• The y-intercept is 4, the equation should be y = -2x + 4
• The slope is -1/2, the equation should be
   y = -1/2x + 5
• The y-intercept is -5, the equation should be y = -2x - 5

Write the equation of a line that passes through the point (2,-4) and has a slope of 4.

• y=4x +12
• y=-4x-12
• y= 4x - 12
• y= 4x -4

Write the equation of a line that passes through the point (1,4) and has a slope of 9.

• y= 9x-4
• y= 9x-5
• y= 9x+4
• y= 9x+5
