Which of these represents point-slope form of a linear equation?

• y - y₁ = m(x - x₁)

• Ax + By = C

• y = mx + b

Slopes of parallel lines are...

• opposite reciprocals.

• opposites.

• identical.

• always 7.

Slopes of perpendicular lines are...

• opposite reciprocals.

• opposites.

• identical.

• always 7.

y = -2/3x + 2
y = 3/2x + 9
These lines are...

• Parallel

• Perpendicular

• Neither

Which of the following lines goes through the point        (-3, 4) and is perpendicular to  y = 3/2x + 6?

• y = 3/2x - 6

• y = 2/3x + 3

• y = -2/3x - 2

• y = -2/3x + 2

• I checked my work and I do not understand my mistake

• I got the last question correct

• I did not check my work

• y - 5 = 2 (x + 4)

• y - 5 = 2 (x - 4)
