Question

Jalen is rock climbing. He starts at 12 feet above sea level. He climbs at a constant rate. After 11 minutes, he is at 21.68 feet.Which equation shows how Jalen’s height, y, depends on the number of minutes, x, it takes him to climb?(1 point)Responsesy=3.06x+12y is equal to 3 point 0 6 x plus 12y=1.97xy is equal to 1 point 9 7 xy=−0.88x+12y is equal to negative 0 point 8 8 x plus 12y=0.88x+12

Answer 1

Start at 12 ft, slope = (21.68 − 12)/11 = 9.68/11 = 0.88. So the linear equation is

y = 0.88x + 12.
