Hey there!
The equation, of a st. line that passes through point (5,9) is,

Put the values,

It is 1st equation.
Now, another equation is,
y = 3x-1.........(ii)
Comparing the equation with y = mx+c.
Slope (m2)= 3
As per the parallel lines,
m1=m2=3
Putting,
the value of m1 in equation(i)
(y-9)= 3(x-5)
y-9= 3x - 15
y = 3x - 6.
So, Krista equation is correct.

Answer:
Area = 88 square units
Step-by-step explanation:
The length of the blue rectangle can be found by subtracting 15 and 4, which equals 11. The width of the blue rectangle can be found by subtracting 6 from 14, which equals 8.
area = length x width
area = 11 x 8
area = 88 square units
<h2>
Hello!</h2>
The answer is:
The slope of the hill is equal to 2.
<h2>Why?</h2>
To solve the problem, we need to remember that the slope of a line, is the rate of increase or decrease of the line.
From the statement we know that the tallest peak of the roller coaster is 310 feet (y), while the roller coaster travels 155 horizontal feet (x), so, calculating we have:

Then, substituting the given information and calculating, we have:

We have that the slope of the hill is equal to 2.
Have a nice day!
