What is the equation of the line that is parallel to the given line and passes through the point (−4,−6 )?
first you'll have to find the slope of your given points -- but i'll save you the time and let you know that the slope is 0. y2 - y1 in this case would be (4 - 4), aka 0. if you have a slope of 0, your line will be horizontal.
so a line that passes through (-4, -6) that is parallel with a horizontal line will have to be a horizontal line as well. all you have to do is take the y-value of that point and turn it into a y = mx + b equation:
y = -6
that satisfies both requirements -- it passes through (-4, -6) and is parallel with the line y = 4 (y = 4 is the line you get from the given points)
The equation of line that is parallel to the given line and passes through the point \((-4,-6)\) is \(y=-6\).
The slope of a horizontal line is zero.
Slopes of two parallel lines are same.
So, the slope of the required line is \(0\).
The required line passes through the point \((-4,-6)\).
The point slope form of a line is \(y-y_1=m(x-x_1)\), where, \(m\) is the slope.
Substitute \(m=0, y_1=-6\) and \(x_1=-4\) in the above equation.
\(y-(-6)=0(x-(-4))\)
\(y+6=0\)
\(y=-6\)
Therefore the equation of required line is \(y=-6\).
