Slope, Slope-Intercept Form, Parallel Equation

Write an equation of a line perpendicular to
y = 2/7x - 5 through (2, -3)

• y = -7/2x + 4

• y = -4x - 7/2

• y = 4x - 7/2

• y = 7/2x + 4

Write an equation for a line that is perpendicular to the graph shown and passes through the point (4,-1)

• y = 2x + 3

• y = 1/2x - 3

• y = 1/2x - 1

• y = -2x + 1

Slopes of parallel lines are...

• opposite reciprocals.

• opposites.

• identical.

• always 7.
