The slope formula is the difference of the y values over the difference in the x values. We have a slope, so we will fill in the formula with what we have and then solve for x: 
. Multiply both sides by x-10 to get rid of the fraction. -2(x-10) = 4. Distribute to get -2x+20=4 and -2x = -16. That gives us an x value of 8.
Answer:
l = 2.25 cm
Step-by-step explanation:
given l is inversely proportional to w² then the equation relating them is
l = ← k is the constant of proportion
(i)
to find k use the condition w = 1.5 , l = 16 , then
16 = =
( multiply both sides by 2.25 )
36 = k
l = ← equation of proportion
(ii)
when w = 4 , then
l = =
= 2.25 cm
