Answer:
OR
Step-by-step explanation:
So first you find the difference between the new cost and the old cost:
450 - 370 = 80
So the increase was 80.
When you write it as a fraction you write the increase ( 80 ) over the starting cost ( 370 ).
Thus the answer becomes
But you can always reduce it to its lowest terms thus:

Answer:
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
In which m is the slope and b is the y-intercept.
Perpendicular lines:
When two lines are perpendicular, the multiplication of their slopes is -1.
Perpendicular to y=1/8x+2
This line has slope
So, for the line we want to find the equation, we have that:
So
Find the equation of the line through point (1,−5)
This means that when . We use this to find b. So:
The equation of the line is:
