Joan's nursery specializes in custom-designed landscaping for residential areas. the estimated labor cost associated with a particular landscaping proposal is based on the number of planting trees, 1 shrubs, and so on to be used for the project. for cost-estimating purposes, managers use two hours of labor time for planting of a medium-sized tree. actual times from a sample of 10 plantintings during the past month follow (times in hours):

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

don't report but were is the digram
