Point-slope form I can and I will graph a line and write an equation using point slope form.

What is point-slope form? y – y1 = m(x – x1) Watch This slope = ½; (-3, 2)

Ex. 1) Write in point-slope form - Slope: 1/6; (5,1)

Watch this Graph the line described by each equation – y – 1 = 2(x – 3)

Ex 2) Graph the line described by each equation – y + 1 = - ½ (x + 4)

Watch this Write the equation in slope-intercept form – slope = -4, (-1, -2) is on the line.

Ex 3) Write the equation in slope-intercept form – slope = 3, (-1, 4) is on the line.

Ex 4) Write the equation in slope-intercept form – (1, -4) and (3, 2) are on the line.

Ex 5) Use the intercepts to find two points– x-intercept = -2 and y-intercept = 4

Write an equation, in slope intercept form, to represent the graph.

Watch this The points (4, 8) and (-1, -12) are on a line. Find the intercepts.

Ex 6) The points (10, -3) and (5, 2) are on a line. Find the intercepts.

More Graphing y + 2 = -2(x + 4)

More Graphing y + 1 = - ½ (x + 4)
