None. Different people prefer different ways of working.
The y-intercept, together with the slope of the line, can also be used in graphing linear equations. The slope and y-intercept of a line can be obtained easily by inspection if the equeation of the line is of the form y=mx+b where m is the slope and b is the y-intercept.
its useful in graphing! equations, inequalities, ect pretty much graphing!
table of values,x and y-intercept and slope and y-intercept
Plot the y-axis, which is the b in the y=mx+b in the slope intercept equation. Then, you put your slope and plot the line.
Put it into slope intercept form and then proceed to use your favorite method of graphing. slope-intercept: y = -3x + 1
When y = 7x +4 the y intercept is 4 and the slope is 7
slope intercept form, rise over run
every time
x = -2 is a vertical line, two units to the left of the y-axis.
It depends on which calculator! If the data is linear, you can estimate the slope of the line and the y-intercept from graphing the data. By graphing the data, you will be able to tell if it forms a straight line or not.
Any function of the form:f(x) = mx + b where "m" is the slope, and "b" is the y-intercept.
Slope intercept is an equation of the form y=mx+b where m is the slope and b is the y-intercept.
