What is the equation in standard form of the line that passes through the point (6, -1) and is parallel to the line 8x+3y=15?

• 8x+3y=-45

• 8x+3y=10

• 8x-3y=45

• 8x-3y=10

Which equation represents a line that passes through the point (3, -4) and has a slope of 7

• y + 4 = 7(x - 3)

• y - 4 = 7(x - 3)

• y + 4 = 7(x + 3)

• y - 4 = 7(x + 3)

Write the standard form of an equation that is perpendicular to
2x - 5y = 10
and passes through (-2, 1).

• 2x + 5y = 1

• 2x - 5y = -9

• 5x + 2y = -8

• 5x - 2y = -12

Write the equation of the line.
