Question

If the slope of the line passing through A (3, m) and B (9, 1) is
then find the value of m.​

Answer 1

Correct Question :- If the slope of the line passing through A (3, m) and B (9, 1) is 2 then find the value of m. ?

Solution :-

we know that,

• slope of the line passing through (x1, y1) and (x2, y2) = (y2 - y1)/(x2 - x1) .

given that,

• x1 = 3
• x2 = m
• y1 = 9
• y2 = 1

so,

→ (y2 - y1)/(x2 - x1) = 2

→ (1 - 9) / (m - 3) = 2

→ (-8) = 2(m - 3)

→ m - 3 = (-4)

→ m = (-4) + 3

→ m = (-1) (Ans.)
