Use the graph to write a linear function that relates y to I.
(2, 2)
(-2, 0)
(0, 1)
(-4, -1)

y = 1/2.x + 1 or... 2y = x + 2

Step-by-step explanation:

m = (y2 - y1)/(x2 - x1):

m = (1 - 0)/(0 - (-2))

m = 1/2

y - y1 = m(x - x1):

y - 0 = 1/2(x - (-2))

2y = x + 2

y = 1/2.x + 1

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
