Question 1011791: I have one question that has three parts to it part A , Part B, and Part C
part a is Can you give me your definition of Linear Equations?
Part B is there a formula for linear equations?
Part C is how can i memorize how to solve for linear equations using statement and reason.
Answer by MathLover1(20850) (Show Source): You can put this solution on YOUR website!
part a: An equation that makes a straight line when it is graphed.
Often written in the form:
what it means:
= how far up
= how far along
= Slope or Gradient (how steep the line is)
= the y-intercept (where the line crosses the y axis)
How do you find "" and ""?

is easy: just see where the line crosses the axis and you do it by setting in given equation and solving for
(the Slope) needs some calculation:
which means if you are given two points that lie on a line and their coordinates are (,) and (,), then slope is

Example:
=> => => y-intercept is at (,)
=>
to graph it make a table for two points
|
|...we already have it
|.....choose any value for and find the matching value for ; if then =>
plot points and draw a line through

Example: you might be given a graph like this

and asked to find the equation of that line
first what we see from the graph is that the line goes through origin; so, we know that
so, your equation will be or just and we need to find a slope
as you see from a graph, if that and if that
so, you have points
(,)=(,)
and
(,)=(,)

then you can find the slope:

and your equation is
