When given a point and a slope, what is the first step in writing an equation in point-slope form?

• Find the y-intercept

• Graph the line

• Identify the coordinates of the point and the slope

• Convert to slope-intercept form

If the given point is (-3, 4) and the slope is -1/4, what is the equation in point-slope form?

Given two points, what is the next step after finding the slope to write the equation in point-slope form?

• Choose one of the points to use in the equation

• Find the y-intercept

• Convert to standard form

• Graph the points

What is the point-slope form equation for the points (1, -2) and (3, 6) with a slope of 4?

• y + 2 = 4(x - 1)

• y - 6 = 4(x - 3)

• y - 2 = 4(x + 1)

• y + 6 = 4(x + 3)

How do you convert the point-slope form equation y + 1 = -1/2(x - 7) to slope-intercept form?
