Definition Of A Slope
Anahi Perales
The Slope of a line is determined by the
ratio between any two points that lie on
the line. All linear relationships have a
constant rate of change. The slope of
a line is what determines how
steep or flat it looks on a graph .
SLOPE VOCABULARY Linear Equation:
an equation whose graph is a line
Y-Intercept- the y-coordinate of the point where a line crosses the y-axis
Slope-Intercept Form- x=mx+b where m=slope & b=y-intercept

GRAPHING LINES IN SLOPE-INTERCEPT
FORMFormula for slope interceptform =
y = mx + b
RATE OF CHANGE & SLOPE
In Algebra, slope is defined as the rise over the run. This is written as a fraction like this

SLOPE OF A LINE
If line goes up from LEFT TO RIGHT , it’s called a POSITIVE SLOPE.If line goes from RIGHT TO LEFT , it’s called a NEGATIVE SLOPE.
The rise is how much you rise in the graph . It tells you how much to go up or down.
The run is how much you move to the left or right in the graph

RULES ON HOW TO GRAPH SLOPE
The slope of a line is the ratio of the change in y over the change in x.
Simply put, find the difference of both the y and x coordinates and
place them in a ratio. Pick two points on the line. Because you are using two sets of ordered
pairs both having x and y values, a subscript must be used to
distinguish between the two values.Juanita Lozano

EXAMPLE OF SLOPE INTERCEPT
y=5x+3 is an example of the Slope Intercept Form and represents the equation of a line with a slope of 5 and a y-intercept of 3 . y= −2x + 6 represents the equation of a line with a slope of −2 and a y-intercept of 6 .
In general slope intercept formula is y=mx+b.*m-slope of a line*b- the y-intercept
Word problem for slope
Yecenia Hernandez
The average lifespan of American women has been tracked, and the model for the data is y = 0.2t + 73, where t = 0 corresponds to 1960. Explain the meaning of the slope and y-intercept.
What was the slope? It is m = 0.2 because it increase by 1 in the input variable t (that is for every year that it increases) the value of the output y would increase by 0.2
