The expression used to represent the amount of work done by person 1 is 1/15, whereas when it comes to person 2 it is 1/30.
You use 1/15 since it is the fifteenth of one hour.

Which graphed line represents an equation of a line with a slope of -1 and a point on the line of (1, - 1)? A) red line
mamaluj [8]

Answer:

y = -x

Step-by-step explanation:

slope = change in y/change in x

slope = -1

Find the y-intercept

x value difference between (0,0) and (1,-1) = 1

if change in x = 1 then change in y = -1 so y-intercept = -1 + 1 = 0

y = -x + 0
