Question

17. Find an equation for the line passing

through each pair of points.
a) A(3, 2) and B(6, 3)

Answer 1

Explanation:

(3,2),(6,3)

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

slope = (3 - 2) / (6 - 3) = 1/3

y = mx + b

slope(m) = 1/3

use either of ur points...(3,2)...x = 3 and y= 2

now sub and find b, the y int

2 = 1/3(3) + b

2 = 1 + b

2 - 1 = b

1 = b

so ur equation is : y = 1/3x + 1
