Y=3/5x is the correct answer
Answer:
i need to see the figure
Step-by-step explanation:
First of all, we need to find the slope of the given line, writing it in the
form and reading the
coefficient:

So, the slope is 
If a line with slope
is perpendicular to a line with slope
, the following relationship holds:

So, the slope of our line must satisfy

So, we need the equation of a line with slope 1 and passing through (4,7). Given the slope
and a point
of a given line, its equation is given by

So, if you plug your values, you have

Answer:
a) 122.5 m ; b) 10 s
Step-by-step explanation:
Just use the given equation and plug in what you know.
a)
d = 4.9t^2
d = 4.9(5^2)
d = 4.9 * 25
d = 122.5 m
b)
d = 4.9t^2
490 = 4.9t^2
100 = t^2
t = 10 s
