Answer:
option 4
Step-by-step explanation:
Take any point on the graph different from (0, 0). For example, (2, 10) and se which function verifies:
y = 10x ----> 10 = 10*2 = 20 so NOT
y = 1/5x ----> 10 = (1/5)*2 = 2/5 so NOT
y = 2x ----> 10 = 2*2 = 4 ----> so NOT
y = 5x ----> 10 = 2*5 = 10 -----> YES!!
So, f(x) = 5x verifies and matches the graph
Answer: The first graph.
This can be found by looking at the y-intercept and plugging in values for x.
To answer the question above, use substitution. The method involves substituting y of the second term by the expression for y in terms of x of the first term. This is shown below.
(1) y = 5x + 3
(2) y = 4x + 6
Substituting,
5x + 3 = 4x + 6
Solving for x in this equation gives x = 3. Use this value to solve for y in any of the equations,
y = 5(3) + 3 = 18
Therefore, the answer is letter "D. (3, 18)".
