Q. What is the equation of the line that passes through the point (−5,7) and has a slope of 0 ?Answer:
Understand Line Characteristics: Understand the characteristics of the line.A line with a slope of 0 is horizontal. This means that for any x-value, the y-value remains constant. Since the line passes through the point (−5,7), the y-value for all points on the line will be 7.
Write Line Equation: Write the equation of the line.For a horizontal line, the equation does not involve x, because the y-value does not change as x changes. The equation of a horizontal line is simply y=[constant y-value].
Substitute Known Y-Value: Substitute the known y-value into the equation.Since the line passes through the point (−5,7) and has a slope of 0, the constant y-value is 7. Therefore, the equation of the line is y=7.
