An equation represents a line that passes through (-2, 4) and has a slope of 2/5 is y-4 = 2/5(x+2)
<h3>Equation of a line</h3>
The equation of a line in point-slope form is expressed as;
y-y1 = m(x - x1)
where
m is the slope
(x1, y1) is any pint on the line
Substitute the given parameter
y - 4 = 2/5(x-(-2))
y-4 = 2/5(x+2)
Hence an equation represents a line that passes through (-2, 4) and has a slope of 2/5 is y-4 = 2/5(x+2)

Answer:
37.68
Step-by-step explanation:
C(circumference)= 2pi r
If the diameter is 12, the r adius is 6
plug into equation
2(pi)(6)
=12pi
=37.68
U have an arithmetic sequence with a common difference of 3
A(n) = -4 + (n-1) * 3
Answer:
7.0%
Step-by-step explanation:
Here, we want to get the value of the percentage increase
mathematically, we have the formula for this as follows ;
(new value - old value/old value * 100%
from the question, old value is 8,300 ft and the new value is 8,881 ft
So we have the percentage increase as follows;
(8,881 - 8,300)/8,300 * 100%
= 7.0%
