What is the y-intercept of the line graphed below?

• 3

• 4

• -3

• 4/3

Write an equation of the line in point slope form containing (-1,1) and (4,-9).

• y +1 = - 2(x - 1)

• y = -2x - 1

• y - 1 = - 2(x + 1)

• 2x + y = -1

Put this into standard form:

y = 3x + 2

• y + 3x = 2

• 3x + y = 2

• 3x - y = - 2

• 3x - 2y = 2

Write the standard form of the equation for the line:

y = 1/4 x + 4

• x + 4y = 8

• x - 4y = -16

• y = x + 16

• 4y + x = 8

Write in standard form: 8x = -5y + 3

• 8x - 5y = 3

• 8x + 5y = 3

• -8x - 5y = 3

• -8x + 5y = 3
