What is the formula for point-slope form?

• y + y1 = m(x + x1)

• y = m(x + x1)

• y = mx + b

• y - y1 = m(x - x1)

• Two slopes

• A slope and a y-intercept

• A point and a slope

• Two points

If given a point (4, 7) and a slope of 3, what is the first step in using point-slope form?

• Substitute the point and slope into y - y1 = m(x - x1)

• Find the y-intercept

• Substitute the point and slope into y = mx + b

• Find the x-intercept

What should you do after distributing the slope in the point-slope form equation?

• Combine like terms

• Divide by the slope

• Find the y-intercept

• Find the x-intercept
