For this case we have that by definition, the equation of the line in the slope-intersection form is given by:
Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
We have the following points through which the line passes:
We find the slope of the line:
Thus, the equation of the line is of the form:
We substitute one of the points and find b:
Finally, the equation is:
Answer:
Answer:
Step-by-step explanation:
Factorise the numerator and denominator
x² - x - 6 = (x - 3)(x + 2)
x² + 2x - 15 = (x - 3)(x + 5)
Hence
=
Cancel the factor (x - 3) on the numerator/ denominator leaving
