Question

7. Find the slope of a line passing through the points A(3-7)
B(2,-5) and also find its equation​

Answer 1

Answer:

2x + y + 1 = 0

Step-by-step explanation:

Slope = (y2 - y1)/(x2 - x1)

= (-5 +7)/(2 - 3)

= - 2

Therefore, equation is:

=> y - (-5) = -2(x - 2)

=> y + 5 = -2x + 4

=> 2x + y + 1 = 0

Answer 2

Step-by-step explanation:

Slope = y2-y1/x2-x1

          = -7-(-5)/3-2

          = -2

By point slope formula,

                y - y1 = m[x - x1]

                y - [-7] = [-2][x - 3]

                y + 7 = -2x + 6

                y + 2x + 1 = 0
