The correct answer is A) y - 4 = -2/5(x + 1)
We know this because of the basic form of point slope form, which is shown below.
y - y1 = m(x - x1)
In which the point (x1, y1) is on the graph and m is the slope. When counting the slope, we can see that it is -2/5 based on the fact that for every two spaces the graph travels down, it moves to the right five. This eliminates options C and D and gives us this form to work with.
y - y1 = -2/5(x - x1)
Now we have the point (-1, 4), so we can plug this in to match it with a formula.
y - 4 = -2/5(x - -1)
y - 4 = -2/5(x + 1)

Given:
Area of a rectangle = 4 square meters
wight = 1/5 meter
find the length
Area of a rectangle = length * width
length = area / width
length = 4 m² ÷ 1/5 m
length = 4 m² * 5/1m
length = 20 m
length is 20 meters.
Area = 20 m * 1/5 m = 20 m² / 5 = 4m²
Answer:
f(x) = 2(x + 3)²
Step-by-step explanation:
Parent Graph: f(x) = a(bx - h)² + k
<em>a</em> is vertical shrink/stretch
<em>b</em> is horizontal shrink/stretch
<em>h</em> is horizontal movement left/right
<em>k</em> is vertical movement up/down
<em>h, k</em> is vertex
Step 1: Define variables
h = -3
k = 0
a = 2
Step 2: Write quadratic
f(x) = 2(x + 3)²
