Equation of y-intercept -1 parallel y=-1/2x-4

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

According to the statement we have the following equation:

The slope is:

By definition, if two lines are parallel then their slopes are equal. Thus, a parallel line will have slope. Therefore, the equation will be of the form:

In the statement they tell us that substituting we have:

The equation is:

it is x=-4

step-by-step explanation:

if you was gonna solve for a, a is a   < -12
