Answer:
I don't understand the question.
Step-by-step explanation:
I don't know how to explore the slope intercept line equation.
However, 'b' is the y axis intercept (the point where is crosses the y axis and 'm' is the slope of the line. The 'm' and the 'b' can be positive or negative numbers.
A positive 'm' is a line that goes 'up' (the y value increases from the left to right) and a negative 'm' is a line that goes 'down' (the y value decreases from left to right).
That could be expressed in two different ways ... because
there are no parentheses in your question.
One way:
Call the number ' N ' .
Nine plus the number is (9 + N)
That much times 14 is 14(9 + N) .
The other way:
Call the number ' N '.
The number times 14 is 14N
Nine plus that is 9 + 14N .
Answer:
(13+9)+4=26
explaiation
the order of numbers in an addition problems doesn't affect the Sum
Let's assume
boiling point is y
altitude is x
we are given
This relationship between altitude and boiling point is linear
At an altitude of 1000 feet, water boils at 210°F
so, first point is (1000,210)
so, x1=1000 , y1=210
At an altitude of 3000 feet, water boils at 206°F
so, second point is (3000,206)
so, x2=3000,y2=206
now, we can find slope

now, we can plug values


now, we can use point slope form of line

so, we can plug it

so, point slope form of line is

now, we can plug x=8000
and then we can solve for y


So,
the boiling point of water at an altitude of 8000 feet is 196°F..........Answer
