This is a free lesson from our course in Algebra I
In this lesson you'll learn how to calculate and determine equation of a line
from its slope and intercept. The final form of equation of the line is known as
the slope and intercept form, and may be already known to many learners. Generally
speaking, if we know that a line has slope m and a y-intercept of (0, b),
then the slope-intercept form of the equation of the line is y = mx
+ b. To be able to use slope intercept form, all that you need to be able to :
• find the slope of a line and
• find the y-intercept of a line. (More text below video...)
(Continued from above)
In general, the slope intercept form assumes the fomula: y= mx +b.
where, m = slope of the line and
b = y-intercept
y = 7x + 8 is an example of the Slope Intercept Form and represents the equation of a line with a slope of 7 and
a y-intercept of 8 ."
