a) Complete the table, using the equation.
b) Write the two points you gave in the
table as ordered pairs. These points are
called solution points. Plug these
coordinates onto the equation and show
that they make a true statement.

d) Plot the two points on the graph. Draw a
line exactly through the two points.
e) Find a different point on that is on your
line. Check that this point is also a solution
to the equation

f) Will any point on the line be a solution point?
g) Choose five additional x-coordinates. Find the corresponding ycoordinates using the equation
Plot the five points on the graph. Do the points fall on your original line?
h) Will any point that is a solution in the equation fall on the line? Explain.
solutions - the points on the line are solution points because the
coordinates are values that make the equation true
The wind speed (y) of a tropical
storm can be represented by the
equation y = 2x + 66, where x is
the number of hours after the
storm enters the Gulf of Mexico.
a) Make a table of values.
b) Make a graph that represents
the speed of the storm.
c) When does the storm
become a hurricane?
