The equation of a line starting from two points is:
From the first point you get: x1 = -1, y1 = -2
From the second point you get: x2 = 3, y2 = 10
Replace x1, y1, x2, y2 in the equation of the line and you get:
From this you get the equation of your line:
From the first point you get: x1 = -1, y1 = -2
From the second point you get: x2 = 3, y2 = 10
Replace x1, y1, x2, y2 in the equation of the line and you get:
From this you get the equation of your line:

Step-by-step explanation:
To obtain x-intercepts, we need to give certain value, specifically .
However, in case of a rational function, we must make sure that doesn't makes the denominator null, beacuse in that case the function is undefined.
Therefore, for x-intercepts we must say
