Ineed to interpret the slope of the graph..

Rate of change of ambient temperature with respect to altitude.

Step-by-step explanation:

Interpretation:  As altitude above sea level increases (from zero to 15 thou of feet and beyond), the ambient temperature drops (from 75 degrees F to 0 and below).  Thus, the (negative) slope of this line signifies the rate of change of temperature with respect to altitude.

-18 degrees is the answer : )

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
