Can you please help me graph x+y=0
vaieri [72.5K]
If you subtract x from each side, it says  Y = -x .
That tells you that the slope of the graph is -1, and the y-intercept is zero.

The graph is a straight line, passing through the origin.
It slopes DOWN from left to right, at an angle of 45 degrees.

IRISSAK [1]

Answer:

72 km/h

Step-by-step explanation:

We need to convert units

so:

20 m    -----  1 km -------- 3600 s

1 s         -----  1000 m ----1 h

and solve ot

20 x 1 x 3600 s = 72000  we multiply  numerators

1s x 1000 m x 1 h = 1000  we multiply denominators

we divide de results 72000/1000 = 72
