Writing the Equation of a Line - YourTeacher.com - Algebra Help

For a complete lesson on writing the equation of a line, go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn to write the equation of a line in slope-intercept form using a table of ordered pairs. The first step is to determine if the ordered pairs in the table lie on a line, so that slope-intercept form, or y = mx + b form, can be used to write the equation of the line. If the rate of change is constant, then the ordered pairs lie on a line. Next, to find the slope of the line, remember that the rate of change is equal to the slope. To find the y-intercept, substitute the slope in for m in the formula y = mx + b, and substitute a given ordered pair in the table for x and y in the formula, then solve for b. Finally, substitute the values for m and b into the formula y = mx + b to write the equation of the line.

why are all the good teachers on you tube and the retarded ones in the class room???

[roxy31512]

Wow, she has neat writing!

[Kora4534]

@ChinoPR001 You find the slope, and you usually have the point, so work from there

[KickBackBangz]

She sounds so annoying -_-

i found it really hard to listen to her.

[Daelynbluberries]

@louthomasTV you divide 3 by 4 and you get .75 and .75 times 12 equals 9 hope i helped

[greatgodKT]

she even teach better than my math teacher, what the hell?
