3.1 Notes Part 2 - Point-Slope Form

Given the equation y - y1 = m(x - x1), what does 'm' represent?

• Y-intercept

• X-intercept

• Slope

• Point on the line

In the point-slope form y - y1 = m(x - x1), how are the coordinates (x1, y1) derived from the equation?

• They are taken directly as they appear in the equation.

• They are the opposite signs of what appears in the equation.

• x1 is the opposite sign, y1 is the same sign.

• x1 is the same sign, y1 is the opposite sign.

What is the Y-intercept of the line represented by the equation y - 1 = -1/2(x - 2)?

• (0, 1)

• (0, 2)

• (2, 0)

• (4, 0)

What is the X-intercept of the line represented by the equation y - 1 = -1/2(x - 2)?

• (0, 4)

What is the slope of the line represented by the equation y + 3 = (3/4)(x + 4)?

• 3/4

• -3/4

• 4/3

• -4/3

Which point lies on the line represented by the equation y + 3 = (3/4)(x + 4)?

• (4, 3)

• (-4, -3)

• (3, 4)
