TEST: Linear Functions

Which is the correctly substituted point-slope form?
Slope: -2
Point: (6, 8)
Be careful!

• y - 8 = -2(x - 6)
• y - 8 = 6(x + 2)
• y + 8 = -2(x + 6)
• y - 6 = -2(x - 8)

Which is the correctly substituted point-slope form?

Slope: 3

Point: (4, -1)

Be careful!

• y +1 = 3(x - 4)

• y - 1 = 3(x - 4)

• y + 1 = 3 (x + 4)

• y - 1 = 3( x + 4)

Which is the correct slope-intercept form?
y - 4 = 5(x + 1)

• y = 5x + 9
• y = 4x + 9
• y = 5x - 1
• y = 5x + 1
