Find the equation of the line that is perpendicular to the line y = 4 and passes through the point (-2, 1).

x = - 2

Step-by-step explanation:

y = 4 is the equation of a horizontal line parallel to the x- axis.

Thus a perpendicular line will be vertical and parallel to the y- axis.

The equation of a vertical line is

x = c

where c is the value of the x- coordinates the line passes through.

The line passes through (- 2, 1) with x- coordinate - 2, thus

x = - 2 ← equation of perpendicular line

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
