What is the point-slope form of the equation if the slope is 8/3 and the point is (2, 3)?

• y - 3 = 8/3 * (x + 2)

• y + 3 = 8/3 * (x - 2)

• y + 3 = 8/3 * (x + 2)

• y - 3 = 8/3 * (x - 2)

What is the slope-intercept form of the equation y - 3 = 8/3 * (x - 2)?

• y = 8/3x - 7/3

• y = 3/8x - 7/3

• y = 3/8x + 7/3

• y = 8/3x + 7/3

If the rate of change is 2/5 and the point is (4, 1), what is the point-slope form of the equation?

• y - 1 = 2/5 * (x + 4)

• y + 1 = 2/5 * (x - 4)

• y - 1 = 2/5 * (x - 4)

• y + 1 = 2/5 * (x + 4)

What is the equivalent form of y - 1 = 2/5 * (x - 4)?

• y + 1 = 2/5 * (x + 4)

• y + 1 = 2/5 * (x - 4)

• y + 1 = 2/5 * (x - 4)

• y - 1 = 2/5 * (x + 4)
