Question

The equation y=14x−74 represents a function. What are the missing coordinates of the points that lie on the graph of this function? Enter your answers in the boxes below.

( , −1.75)
(−4, )
( , −6)

Answer 1

Answer:

1. x ≈ 5.161

2. y = -130

3. x ≈ 4.857

Step-by-step explanation:

Given y=14x−74

Here, we will substitute the given values of x or y and find the unknown value for these three cases,

Case I

( , −1.75)

−1.75=14x-74

14x=74-1.75=72.25

x=72.25/14

x≈5.161

Case II

(−4, )

y=14×(−4) -74=-56-74

y= -130

Case III

( , −6)

-6=14x-74

14x=74-6=68

x=68/14

x≈4.857
