The equation for line is
Explanation:
It is given that the line passes through the point with x-intercept = -2
The x intercept is the value of x when y = 0.
Thus, it can be written in coordinate as
Now, we shall determine the slope using the points and
Substituting, we get,
Thus, the slope is
Now, we shall substitute the point and slope
in the point-slope formula
, we get,
Multiplying both sides by 4, we get,
Subtracting both sides by 12,
Dividing both sides by 4, we get,
Thus, the equation of the line is
