Answer:
Let x represent the rate of the current
d = r*t Or t = d/r
%2812mi%2F%286mph-x%29%29+=+%2824mi%2F%286mph%2Bx%29%29
cross multiply
24*(6-x) =12*(6+x)
12*6 = 36x
2mph = x, the rate of the current
checking our answer
12mi/4mph = 24mi/8mph = 3 hr

y = 4x + 12
Step-by-step explanation:
y = mx + b
'm' represents slope
'b' represents the y-intercept
use the slope and the point (3,24) as your x and y inputs to find 'b'
24 = 4(3) + b
24 = 12 + b
b = 12
y = 4x + 12
