Use the graph.

ben says that the equation y = 2x + 1 represents the line on the graph.
what error did ben make?
a. ben switched x and y.
b. ben found the y-intercept incorrectly.
c. ben forgot to write a negative sign in front of the slope.
d. ben switched the rise and the run when writing the slope.

The correct option is C) Ben forgot to write a negative sign in front of the slope.

Step-by-step explanation:

Consider the provided graph.

From the graph we can be concluded that the line is passing through the point (0,1) and (1,-1).

Find the slope of the function by using the above point:

Slope formula:  

The slope of the line is -2

The slope intercept form is:

Where m is the slope and b is the y intercept.

y intercept is a point where the line intersect the y axis.

From the graph the y intercept is 1.

Now substitute the value of slope and y intercept in slope intercept form.

Now consider the equation of Ben y = 2x + 1.

Ben's equation is correct but he forgot to write a negative sign in front of slope.

Hence, the correct option is C) Ben forgot to write a negative sign in front of the slope.
