Question

An object moves at a constant rate. The graph shows the object's height at different times.

Which equation represents the situation?




A.
y = −15x + 900


B.
y = −15x − 900




C.
y = 15x − 900


D.
y = 15x + 900

Answer 1

answer is a

y=-15x+900

Answer 2

Well we know the slope is negative so y=-15 then we can find the y intercept which is positive 900. SO the correct answer would be A.
