The curve is y = sqrt{x}.
Replace x in the curve with 1 and then with 4 to find your point.
y = sqrt{1}
y = 1
First point (1, 1).
y = sqrt{4}
y = 2
Second point (4, 2).
Take it from here.
Answer:
37
Step-by-step explanation:
Let the initial number be
.
Initial number:
Units digit = y
Tens digit = x
The units digit of a 2-digit number is 1 more than twice the tens digit, then

Reversed number is 
If the new number is 36 more than the original number, then

Simplify this equation:

Substitute
into the equation 

Initial number: 37
1. 9 feet revelent to the surface
2. 19 points
Parallel lines share the same slope. y=3x+7 has a slope of 3, so that is the slope of the parallel line. Then use y=mx+b an plug in (2,4).
y=3x+b
4=3(2)+b
4=6+b
b=-2
So the equation is y=3x-2
