How to Graph a Line
PH4L
Using a table of values
plot the order pairs
graph the line by joing the points
get the ordered pairs
subtitute values of x in the equation
find the values of y
now you have the ordered pairs :check:
write the equation in y=mx+b form
tutorial video 1
tuturial video 2
ixl practice
Using 2 points
join the 2 points to draw the line
tutorial video
ixl practice
plot the 2 points
Using a point and a slope
plot the point
use the slope (rise/run) to plot another point

ixl practice
Using y=mx+b
Rarrange the equation if needed / you should have only y on the left hand side of the equation
tutorial video
plot the y-intercept (b) on the y axis
If m is positive count up the numerator and count the donominater to the right, then plot the point
If m is negative count down the numerator and count the donominater to the right, then plot the point.
Join the the y-intercept and the point to graph the line
ixl practice
if m is a whole number then denominator is 1, we move to the right one
