Suppose the maximum healthy weight for a person who is 5 feet 9 inches tall is 150 pounds, and the maximum healthy weight for someone 6 feet 7 inches tall is 200 pounds. The relationship between weight and height here is linear.

Question

anonymous · Answer

(a) Find a linear equation that gives the maximum healthy weight y for a person whose height is x inches over 4 feet 9 inches. (Thus x = 0 corresponds to 4 feet 9 inches and x = 3 to 5 feet,etc.)

anonymous · Answer

yes that is correct

anonymous · Answer

How do I find the equation?

anonymous · Answer

y=mx+b use the two points you just explained to solve for the slope and the y intercept should correspond with 4 feet 9 inches because that is the starting point for the heights

anonymous · Answer

(12, 150) and (19, 200)?

anonymous · Answer

$$y=\frac{ 50 }{ 7 }x+\frac{ 450 }{ 7 }$$ 

Is that correct?
