Find the slope of a line which passes through the points(i) (0, 0) and

1.	Find the slope of a line which passes through the points(i) (0, 0) and (4, -2)(ii) (0, -3) and (2, 1)(iii) (2, 5) and (-4, -4)(iv) (-2, 3) and (4, -6)
Answer» If a line passing through (x₁, y₁) & (x₂, y₂) then slope of the line is given by slope = (y₂-y₁/x₂-x₁) (i) Given points are (0,0) and (4,-2) slope = (-2-0/4-0) = -1/2 (ii) Given points are (0, -3) and (2, 1) slope = (1-(-3)/2-0) = 2 (iii) Given points are (2, 5) and (-4, -4) slope = (-4-5/-4-2) = 3/2 = 1.5 (iv) Given points are (-2, 3) and (4, -6) slope = (-6-3/4+2) = - 3/2 = -1.5

Answer»

If a line passing through (x₁, y₁) & (x₂, y₂) then slope of the line is given by slope = (y₂-y₁/x₂-x₁)

(i) Given points are (0,0) and (4,-2)

slope = (-2-0/4-0) = -1/2

(ii) Given points are (0, -3) and (2, 1)

slope = (1-(-3)/2-0) = 2

(iii) Given points are (2, 5) and (-4, -4)

slope = (-4-5/-4-2) = 3/2 = 1.5

(iv) Given points are (-2, 3) and (4, -6)

slope = (-6-3/4+2) = - 3/2 = -1.5
