Hi Addie;
In class, did you cover
y=mx+b
?
m=slope=(y_{2}y_{1})/(x_{2}x_{1})
b=yintercept. This is the value of y when x=0. It is the position in which the line crosses the yaxis.
The question was...
Given the graph of an equations, where would you look on the graph to find the solutions to the equation that goes with the graph?
The answer I would suggest is...
I would look at the position on the yaxis when x=0. This is the yintercept, also known as b in the equation known as y=mx+b. The m in such equation is the slope. This is the difference between any two coordinates. It
is the value of each ycoordinate, subtracted from each other. Such subtracted result is divided by the corresponding two xcoordinates, also subtracted from each other.
