Since there are no given graphs, allow me to give an example of a linear equation.

You are given two points, (-1, 10) and (5, 8). You are required to find the equation in slope intercept form given the points. The equation of a slope intercept form is y = mx + b. Where m is the slope and b is the y-intercept. By definition, slope, m, is the rise over run or the difference of y over the difference of x.

m = y2-y1/x2-x1

Let us denote y2=8, y1=10, x2=5 and x1=-1 and we get

m = 8-10/5-(-1)

m = -1/3, a negative slope means it is rising to the left of the graph.

Since the slope passes the two points, it also passes the y-intercept. Choose one of the points, (-1, 10) and substitute it to y = mx + b.

y = mx + b

10 = (-1/3)(-1) + b

b = 29/3

The equation now is y = -1/3x + 29/3.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
