Question

The graph below shows four straight lines, W, X, Y, and Z.

Answer 1

Hello : 
answer : B : line X  because : f(o)=5 ( passes by : (0,5) )

Answer 2

Answer:

Option B. Line X

Step-by-step explanation:

The graph shows four straight lines W, X, Y, Z.

We have to identify the line which represents the function f(x) = 3x + 5

The given equation is y = 3x + 5, in which slope of the line should be 3 and y- intercept is 5.

In these lines line x is having y-intercept as 5.

Line x passes through (-1, 2) and (0, 5)

So slope of the given line will be = $\frac{y-y'}{x-x'}$

= $\frac{5-2}{0+1}$

= 3

Therefore, option B : Line X is the answer.
