Question 415701
y = -7x + 40


the value of y depends on the value of x.


when x = 0, y = 40
when x = 1, y = -7+40 = 33
when x = 5, y = -35 + 40 = 5


a graph of the equation y = -7x + 40 is shown below:


{{{graph(600,600,-10,10,-50,50,-7x+40,40,33,5)}}}


i drew horizontal lines at y = 40, 33, and 5.


draw a vertical line from the intersection of these horizontal lines with the graph of the equation and you will see that the corresponding x values are 0, 1, and 5 respectively.


the point pairs for (x,y) are:


(0,40)
(1,33)
(5,5)
