Question

Look at the graph shown:

A coordinate plane is shown. A line passes through the y-axis at -1 and through the point 1 comma 2.

Which equation best represents the line?

y = 1 over 3. x − 1
y = 3x − 1
y = −x + 1 over 3.
y = 3x + 1

Answer 1

y = 3x − 1

Explanation:

I got the answer right on the test

Answer 2

y = 3x - 1

Explanation:

Although the coordinate plane is not given, we don't need it to find the solution. We have given all the conditions enough for the solution.

The y-intercept is (-1) and the function passes through the point ( 1, 2 ).

Only the function y = 3x -1 matches these conditions.

We can observe the points in the attached graph.
