Step-by-step explanation:
Answer:
y = 12x - 13
Step-by-step explanation:
The two points you want the line through are ...
... (-4, h(-4)) = (-4, -61)
and
... (2, h(2)) = (2, 11)
The 2-point form of the equation of a line is applicable. For (x1, y1) and (x2, y2), the equation is
... y = (y2-y1)/(x2-x1)·(x-x1) +y1
... y = (-61-11)/(-4-2)·(x -2) + 11 . . . . putting in the point values
... y = 12(x -2) + 11 . . . . . . . . . . . . . simplify
... y = 12x -13 . . . . . . . . . . . . . . . . . eliminate parentheses, collect terms
well, we know his rate is 6/5 lawns/hour that means he can do 6 lawns in 1 hour, well, how many can he do in 50 hours?
![\bf \begin{array}{ccll} lawns&hours\\ \cline{1-2} 6&5\\ x&50 \end{array}\implies \cfrac{6}{x}=\cfrac{5}{50}\implies \cfrac{6}{x}=\cfrac{1}{10}\implies 60 = x](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Bccll%7D%20lawns%26hours%5C%5C%20%5Ccline%7B1-2%7D%206%265%5C%5C%20x%2650%20%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B6%7D%7Bx%7D%3D%5Ccfrac%7B5%7D%7B50%7D%5Cimplies%20%5Ccfrac%7B6%7D%7Bx%7D%3D%5Ccfrac%7B1%7D%7B10%7D%5Cimplies%2060%20%3D%20x)
