Question 627743
<font face="Times New Roman" size="+2">


Plot the points *[tex \LARGE (20,11300)] and *[tex \LARGE (50,17750)] on your coordinate axes and then sketch a line that passes through the two points.  Unless you have some really, really tall paper, you will want to scale your coordinate plane appropriately, say units of 1000 on the vertical axis against units of 5 on the horizontal.


Start with part (c).  First use the two-point form of an equation of a line:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y\ -\ y_1\ =\ \left(\frac{y_1\ -\ y_2}{x_1\ -\ x_2}\right)(x\ -\ x_1) ]


where *[tex \Large \left(x_1,y_1\right)] and *[tex \Large \left(x_2,y_2\right)] are the coordinates of the given points.


Plug in the numbers, do the arithmetic, simplify, and solve for *[tex \LARGE y] in terms of everything else.  Once your equation has the form:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y\ =\ mx\ +\ b]


you have completed part (c).


The answer to part (a) is the coefficient on *[tex \LARGE x] in your answer to (c).


The answer to part (b) is the constant term, i.e., the *[tex \LARGE b] in your answer to part (c).
