Slope Slope Intercept Point Slope Standard Form Parallel and Perpendicular

Write the equation of a line perpendicular to y = 3x - 8 and that passes through the point (-3, -9)

• y + 9 = -1/3(x + 3)

• y - 9 = -1/3(x - 3)

• y + 9 = -3(x + 3)

• y - 9 = 3(x - 3)

write the equation of a line that is parallel to y = -7x + 5 and passes through the point (0, 6)

• y = -7x + 6

• y + 0 = -7(x - 6)

• y = 6

• y + 6 = -7(x - 0)

The name for this equation is. . .

• slope intercept form

• point slope form

• slope

• standard form
