Answer:
Therefore = -3.
Step-by-step explanation:
i) let us say the slope of the line passing through (-2,7) and (4,9) is .
ii) to find the slope of the line passing through two points (, ) and (,) we use the formula m = . Therefore we can say that = = .
iii) let us say the slope of the perpendicular line to the line passing through (-2,7) and (4,9) is
iv) from the formula for the slopes of a line and the line perpendicular to it which is given by × = -1, therefore = -1 ÷ = -3. Therefore = -3
a² + b² = (a + b)² - 2ab
