The equation y = 11x shows that a boat travels at a speed of 11 km/h.

which ordered pair satisfies the equation y = 11x?

a.
(0, 11)

b.
(1, 12)

c.
(2, 22)

d.
(11, 1)

Best lets sub and find out...
y = 11x

(0,11)
11 = 11(0)
11 = 0 (incorrect)
not the first one

(1,12)
12 = 11(1)
12 = 11 (incorrect)
not the second one

(2,22)
22 = 11(2)
22 = 22 (correct)
Here it is :)

let me go ahead and check the last one as well...
(11,1)
1 = 11(11)
1 = 121 (incorrect)

Your answer is C. (2,22)

When you get problems like these, just sub your set of points (x,y) into the equation to see which one satisfies the equation.

The answer is
