Ahighway engineer specifies that a certain section of roadway covering a horizontal distance of 2km should have a downgrade of 8%. compute the change in elevation of this section of road. use the slope formula.

Step-by-step explanation:

A highway engineer wants to compute  the change in elevation of a section of road. The horizontal distance of this section of road is 2km and downgrade is 8%

The slope formula is given by

m = 8% = 8/100

run = y = 2km

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
