The slope (m) of the line graphed is -4/2, because the line goes down 4 (-4) and over 2 (+2), which is change in y over change in x
m = -4/2 = -2
the y-intercept (b) of the line = -1, because the line crosses the vertical line at x=0 at y=-1
now for the equation:
y = mx + b
y = -2x + -1 = -2x - 1
f(x) = -2x-1
the last answer is correct
D. 7.2lbs To find the range all you have to do is subtract the smallest number from the group from the biggest number. And in this case that would be 9.9- 2.7
......what's the question?
Answer:

Step-by-step explanation:
<3 and <4 form a linear pair, so they are supplementary (=180 degrees)
Answer:
x=7
Step-by-step explanation:
2x=20-6
2x=14
x=14/2
x=7
