The given proportional relationship is y = -5x.
Therefore the ratio
y/x = -5 = -5/1
If x changes by 1, then y/x = y/1 = -5.
This means that y changes by -5 when x changes by 1.
The ratio of vertical change is -5:1
The standard equation for a straight line is
y = m*x + c
where
m = the slope,
c = the y-intercept.
Therefore the given relationship is a straight line with a negative slope of -5. This means that y decreases as x increases.
Answer: C
-5:1
The graph decreases from left to right.
Answer:

Step-by-step explanation:
The coordinates of the given quadrilaterals are

The reflection in the line
has the mapping,

We just have to swap the coordinates.
This implies that,




Therefore the correct answer is A.

Answer:
222 miles.
Step-by-step explanation:
<u>Lets create an equation to solve this easier.</u>
<u>Let x represent the miles driven in the truck. </u>
Our equation is 238.51=.98x+20.95
All we have to do now is solve for x.
Subtract 20.95 on both sides.
217.56=.98x
Now divide both sides by .98 to isolate the variable.
222=x
