Joseph plots the speed of his car and time on a scatter plot. The equation for the line of best fit on his scatter plot is y = -15x + 60, where x is the time in hours and y is the speed in miles/hour. Which statement describes the situation correctly?

15x + 60y

Step-by-step explanation:

It just seem right cause u didn't give us a lot of information to find out

Answer

The initial speed is 60 miles/hour, and his speed decreases by 15 miles/hour every hour.

Step-by-step explanation:

i think that might be the answer

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =    

hope this you and
