point slope form:y-2=4(x+1)

then distribute 4 and simplify y-2=4x+4 , y=4x+6 is the slope -y intercept form

then, move 4x on the left side, you get -4x+y=6 , multiply every term by -1, you get 4x-y=-6 which is standard form.

X is inversely proportional to y, and x = 18 when y = 4. Write an equation relating the two
Alenkasestr [34]

Answer:

xy=72

Step-by-step explanation:

If x is inversely porportionaly to y, then for some constant k,

x = \frac{k}{y}\\xy=k

Since y is 4 when x = 18, k is equal to 4*18=72, so the equation is:

xy=72

Eddi Din [679]
To get the constant of proportionality (unit rate) you must find the miles driven in 1 hour. To get this you simply divide 200 by 4...
200÷4=50
So, the constant of proportionality is 50 mph.
