Question

Tiffany compared the graph of y = 7x + 2 to the graph of the linear function

shown in the table.
What is the distance, in units, between the y-intercepts of the two
functions?

Only 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, . ., and / are allowed in your answer.
Answers that are mixed numbers must be entered as an improper fraction or a
decimal

Answer 1

0

Explanation:

so we first have to find the ummmm the slope intercept form for the graph

sooo we must get two points and use the equation y2 - y1/ x2 - x1

(4,15) and (6, 31)

31 - 15/ 6 - 4

16/2

8

sooo rn its:

y = 8x + b

now to find the y-intercept we have to input a point we did NOT use yet.

(8, 47)

47 = 8(8) + b

47 = 64 + b

b = 47 - 64

b = -17

the equation for the table is

y = 8x - 17

soo the y-interecept is when x is 0 so we have to use the equation y2 - y1/ x2 - x1 to find the distance

sooo

(0, 17) [for the table] and (0, 2) [from the equation y = 7x + 2)

17 - 2/0-0

15/0

0

ummm i tried my best here because im learning about something different and i hope this helps you and i hope this is correct!
