Question

plz help What is the equation of the line that passes through the points (-9,7) and (-10, 5)?

Answer 1

Answer:

$(x - x_{1}) = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} (y - y_{1}) \\ (x_{1} \: \: y_{1}) = ( - 9 \: \: 7) \\ (x_{2} \: \: y_{2}) = ( - 10 \: \: 5) \\ put \: the \: values \: in \: above \: formula \\ (x + 9) = \frac{5 - 7}{ - 10 + 9} (y - 7) \\ x + 9 = \frac{ - 2}{ - 1} ( y - 7) \\ x + 9 = 2y - 14 \\ x - 2y = - 23 \\ x - 2y + 23 = 0$

Answer 2

Answer:

ye wala formula lage ga

Step-by-step explanation:

y - y¹/x - x¹ = y² - y¹ / x² - x¹

• y - 7 / x - (-9) = 5 - 7 / (-10) - (-9).
• y -7 / x +9 = (-2) / (-1).
• (-1) (y - 7) = (-2)(x + 9).
• -y + 7 = -2x - 18.
• 2x - y + 18 + 7.
• 2x - y + 25 = 0

ye right answer hai
