Answer 1

plz help

Answer 2

pick two sets of points...
(0,3) and (1,5)
use the slope formula and find the slope
slope(m) = (y2 - y1) / (x2 - x1)
slope(m) = (5 - 3) / (1 - 0)
slope(m) = 2/1 which equals 2.

now use y = mx + b
slope(m) = 2
you can choose any of the points....I will choose (0,3)
now we sub
3 = 2(0) + b
3 = b

your equation is : y = 2x + 3
