P(1, 2), Q(3, 4)
we find the slope dividing the y over the x, that is:
m = (4 - 2)/(3 - 1) = 2/2
m = 1
and then use the line equation for a point and slope:
y - y1 = m(x - x1)
where (x1, y1) is a point through which the line passes, we use P(1,2):
y - 2 = 2(x - 1)
y - 2 = 2x - 2
y = 2x
therefore the slope is 2 and the y-axis intercept is 0

A pleasure boat sets out for a cruise on a river, sailing upstream 24 miles and then turning around and returning to port. The t

sineoko [7]

Answer:

V(w) = 26 miles/hour

Step-by-step explanation:

Let

V(bu) upstream boat speed V(w) water speed

Speed upstream

V(bu) = 24 /144 ⇒ V(b) = 0,167 miles/min

V(bd) = 24/40 V(bd) = 0,6 miles/min

V(bd) = V(b) + V(w)

0,6 -0,167 = V(w)

V(w) = 0,433 miles/min

or equivalent in miles /hour

V(w) = 25.98 miles/hour

V(w) = 26 miles/hour
