answer:
6) Slope= -5/7= -0.7143
7) Slope= -2/1= -2
explanation:
Both points belongs to an decreasing linear function.
look at the 2 attached photos. You can find the slope using a graph.
Well if its going to be going up the same every year then you just have to add $2000 every year until you get to 10 years well idk if im right
Answer:
y = - 4x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ )= (1, - 2) and (x₂, y₂ ) = (2, - 6) ← 2 ordered pairs from the table
m = = = - 4, thus
y = - 4x + c ← is the partial equation
To find c use any ordered pair from the table
Using (1, - 2), then
- 2 = - 4 + c ⇒ c = - 2 + 4 = 2
y = - 4x + 2 ← equation in slope- intercept form
<span>Since it's rectangular, there is a length and width. Let the width be w, and the length is then w+3. The total length of the fence is the perimeter, so 150 = 2*w + 2*(w+3) = 4w+6. Solving for w, this becomes w=(150-6)/4 = 144/4 = 36 feet.</span>
