Horizontal and Vertical Lines
The graph of a relation of the form y = 5 is a line parallel to the x-axis because the y value never
A line parallel to the x-axis is called a horizontal line.
The graph of a relation of the form x = 5 is a lin
Examples of linear equation
-3=x or (-3,0)
y=-3 or (0,-3)
-3/4=x or (-3/4,0)
y=3 or (0,3)
A Timeplot (sometimes called a time series graph) displays values against time. They are similar to x-y
graphs, but while an x-y graph can plot a variety of x variables (for example, height, weight, age),
Timeplot can only display time on the x-a
What is a line graph?
A line graph is used to show how values change. For example, you could plot how your child
grows over time. Line graphs can also be used to show how functions change. A function is
just an equation that gives you a unique
WHAT IS A LINE GRAPH?
A Line Graph is a graph that uses points and
lines to show change overtime. A line graph is
a diagram that show a line joining several
points, or a line that shows the relationship
between the point
Defining the Thesis Statement
What is a thesis statement?
Every paper you write should have a main point, a main idea, or central message. The
argument(s) you make in your paper should reflect this main idea. The sentence that captures
your position on th
y = mx + c
We have seen graphs in the form y = mx + c before.
When a graph is written in the form y = mx + c, m represents the gradient and c represents
the y intercept.
Take the example of the cost of a taxi ride at 1 + 3 per mile. In this case the gradi
