Brooke found the equation of the line passing through the points (–7, 25) and (–4, 13) in slope-intercept form as follows.
question:
what was brooke’s error?
•she found the incorrect slope in step 1.
•she mixed up the x- and y-coordinates when she plugged in the point in step 2.
•she found the incorrect y-intercept in step 2.
•she mixed up the slope and y-intercept when she wrote the equation in step 3.

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:

m: It's the slope

b: It is the cut-off point with the y axis

We have the following points:

Substituting the values:

Thus, the line is of the form:

We substitute one of the points and find "b":

Finally we have to:

The equation es

is only a line? i think so

positive

step-by-step explanation:

the quadrant is facing upwards
