Question

In slope-intercept form, what is the equation of the line passing through the points (2, 13) and (5, 22)

Answer 1

(2,13),(5,22)
slope = (22 - 13) / (5 - 2) = 9/3 = 3

y = mx + b
slope(m) = 3
use either of ur points...(2,13)...x = 2 and y = 13
now sub and find b, the y int
13 = 3(2) + b
13 = 6 + b
13 - 6 = b
7 = b
so ur equation is : y = 3x + 7 <===
