The slope of a trend line that passes through the points (5, 80) and (7, 65) is -7.5.
Step-by-step explanation:
If the line is passing through two points (x1, y1) and (X2, y2). The slope (m) can be calculated using following formula.

In this case,
x1 = 5
x2 = 7
y1 = 80
y2 = 65
By putting the values in formula, we get


or
m = -7.5
Therefore, the slope of a trend line that passes through the points (5, 80) and (7, 65) is -7.5.

Answer:
Is important to remember that the reflection of the point (a,b) across the y-axis is the point (-a,b).
Our original equation is 
And after the reflection respect x we got:

Step-by-step explanation:

Our original equation is 
And after the reflection respect x we got:

Quadrant Four (IV) since the x coordinate is a positive and the y coordinate is a negative.
