उत्तर
The line passing through the points (−7, 4) and (5, 4) is parallel to x-axis.
Explanation:
By formula,
Slope = `(y_2 − y_1)/(x_2 − x_1)`
Substituting values we get:
Slope of line passing through (−7, 4) and (5, 4)
= `(4 − 4)/(5 − (−7))`
= `0/(5+7)`
= `0/12`
= 0
We know that,
Slope of parallel lines are equal.
We know that,
Slope of x-axis = 0.
∴ Slope of line passing through (−7, 4) and (5, 4) = Slope of x-axis.
