Understanding Point-Slope Form

What is the point-slope form of a line equation?

• y - y1 = m(x - x1)

• x = my + b

• y = mx + b

• ax + by = c

In the point-slope form, what does 'm' represent?

• The y-intercept

• The x-coordinate of a point

• The slope of the line

• The y-coordinate of a point

Given a point (4, -1) and a slope of -3, what is the equation of the line in point-slope form?

• y + 1 = -3(x - 4)

• y + 1 = 3(x + 4)

• y - 1 = -3(x + 4)

• y - 1 = 3(x - 4)

What is the slope-intercept form of the equation y + 1 = -3(x - 4)?

• y = 3x + 11

• y = -3x - 11

• y = -3x + 11

• y = 3x - 11

What is the y-intercept of the line with the equation y = -3x + 11?

• (11, 0)

• (-11, 0)

• (0, 11)

• (0, -11)
