Question

What is the equation of the function shown in the graph?

Answer 1

Answer:

y = 3x-1

Third option is correct.

Step-by-step explanation:

From the given graph, we have

y -intercept = -1

And the line passes through the point (1,2)

The slope intercept form of the line is y =mx +b.

where, m is slope and b is y-intercept

Here, b = -1

Hence, the equation is in the form y = mx -1

Now,line passes through the point (1,2)

Substitute x = 1, y = 2 in the equation to find m

2 = 1m-1

3 = m

m = 3

Hence, the equation of the line is y = 3x-1

Answer 2

I believe the answer is y=3x-1 You can put 2 in the place of y and 1 in the place of x and go down the list with knowing just those things and nothing works to get you back to 0,-1 except for y=3x-1
