Answer:
y = (-5/3)x - 4
Explanation:
The equation of a line with slope m that goes through the point (x1, y1) is:
Additionally, two lines are parallel if they have the same slope.
The slope of the line y = (-5/3)x - 2 is (-5/3) because it is the number beside x.
So, the slope of our line is also -5/3.
Therefore, replacing m by -5/3 and (x1, y1) by (-3, 1), we get that the equation of the line is:
Finally, solving for y, we get:
So, the answer is:
y = (-5/3)x - 4
A rational expression is undefined if the denominator is zero. Since the denominator is , the expression is undefined if
