5.6 Day 2 Notes

Name: __________________________________

Today’s Objectives:

I can write an equation in standard form given two points.

Let’s review what standard form is…

Rules for Standard Form

1.

2.

Writing an equation in

standard form given a

slope and a point.

Examples

Steps:

1) Put in Point-Slope Form

2) Put in Slope-Intercept Form (pick your favorite point)

3) Put in Standard Form

1) Write the equation of the line, in STANDARD FORM, that passes through the

point (-1, -2) with a slope of 7.

2) Write the equation of the line, in STANDARD FORM, that passes through the

point (4, 1) with a slope of �

�.

Now you try…

3) Write the equation of the line, in STANDARD FORM, that passes through the point (-4, 1) with a slope of �

�.

2) Put in Point-Slope Form

3) Put in Slope-Intercept Form

4) Put in Standard Form

1) Write the equation of the line., in STANDARD FORM, that passes through the

points (-1, -3) and (1, -5)

2) Write the equation of the line., in STANDARD FORM, that passes through the

points (5, -5) and (3, -1)

� Now you try…

1. Write the equation of the line., in STANDARD FORM, that passes through the points (1, -3) and (-1, -1)

Equation: ______________________

2. Write the equation of the line. in STANDARD FORM, that passes through the points (2, 2) and (-4, -2)

Equation: ______________________

Extra Practice: Write the equation of the line in STANDARD FORM for the given information.

1) Write the equation of the line, in STANDARD FORM, that passes through the point (3, 0) with a

slope of ��

�.

2) Write the equation of the line. in STANDARD FORM, that passes through the points (-2, 2) and (-2, 1)

3) Write the equation of the line. in STANDARD FORM, that passes through the points (-5, -5) and (0, 2)
