Question 415701: y=mx+b.If m=-7,If b+40,What does y equal?
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! 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:
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)
