Solution:

The point slope form of a line is given as:

Where, m is the slope of line

From given,

m = -10

Given point is (1, 4)

Substitute m = -10 and = (1, 4) in given formula

Thus the point-slope equation of the line with slope -10 that goes through

the point (1,4) is found

Thus Option D is correct

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
