X+2y=-9

Solve for Y km

y = - 1/2x - 4.5

Step-by-step explanation:

Step 1:

x + 2y = - 9         Equation

Step 2:

2y = - x - 9       Subtract x on both sides

y = - 1/2x - 4.5             Divide 2 on both sides

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

its kind of blurry. can you put a clearer pic?
