<span> What kind of figure do you get?
For this case a straight line was obtained, whose equation is
</span><span> y = -x
</span><span> In what quadrants does the figure lie?
The figure is in the second quadrant. (See graphic)

Perimeter=sum of side lengths...
P=2L+2W
P=2(L+W), in this case L and W are 30 and 40 so
P=2(30+40)
P=2(70)
P=140
So 140 feet of fencing is needed to replace the fence.
The amount of sod needed is equal to the area which is LW
A=30(40)=1200 ft^2
Answer:
Step-by-step explanation:
Hello!
The equation, y = mx + b is slope-intercept form. In this equation, m is the slope, and b is the y-intercept.
If the baby was exactly 8 pounds when it was born, then the y-intercept is (0, 8) because at zero months, the baby was eight pounds. To find the rate of change, we can use the the y-intercept (0, 8), and the weight of the baby at four months, which is (4, 8 + 3) → (4, 11).
Since we have two points, we can use the slope formula
to find the rate of change.
.
The rate of change is 3/4.
Therefore, the equation that describes the baby's weight is y = 3/4x + 8.
