Question 1172719
<font face="Times New Roman" size="+2">


You are given two points on the graph of a straight line, namely *[tex \LARGE (200,60)] and *[tex \LARGE (500,45)].


Use the Two-Point form of an equation of a line:


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


where *[tex \LARGE (x_1,y_1)] and *[tex \LARGE (x_2,y_2)] are the two given points to write an equation of the straight line.


Then substitute $40 for *[tex \LARGE y] and solve for *[tex \LARGE x] to get the answer to your first question, and then substitute 400 for *[tex \LARGE x] and solve for *[tex \LARGE y] to answer your second question.
