WILL GIVE THE BRAINLIST In the table below x represents miles traveled and y represents the cost to travel by train What is the yintercept of this function 225 class=

Respuesta :

The equation of the graph shown is y-4=4(x+2). The y-intercept should be 12.

Answer:

Option B. 4

Step-by-step explanation:

By the table mentioned by you in the comments that the correct table is

x(miles)   2        5        8     12

y(cost)   8.5   15.25    22    31

As we know that the standard equation of a linear function is represented as

y = mx + c

For the points (2, 8.5) and (5, 15.25)

[tex]Slope(m)=\frac{15.25-8.5}{5-2}=\frac{6.75}{3}=2.25[/tex]

y = 2.25x + c

This function passes through (2, 8.5)

8.5 = 2.25×2 + c

c = 8.5 - 4.5 = 4

Therefore, y- intercept of the function will be option B. 4.
