19-(-39)
19+39=58
is solution as
the two end points are 19 and -39 we should subtract then we get the distance between
Answer: Exponential table
Rearrange them to slope-intercept form
y = 7x + 2
y = -(1/7) x + 8
product of their slopes is 7 * -1/7 = -1 so they are perpendicular
The correct answer is distance, in miles, between the cities
