Answer:
y = - 
x - 3
Step-by-step explanation:
The equation of a line in slope- intercept fprm is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x + 7 is in slope- intercept form
with slope m = 3
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - , thus
y = - x + c ← is the partial equation of the perpendicular line
To find c substitute (3, - 4) into the partial equation
- 4 = - 1 + c ⇒ c = - 4 + 1 = - 3
y = - x - 3 ← equation of perpendicular line

Answer:
7.23km/h
Step-by-step explanation:
Speed = distance/time
Given
distance = 6.36km and
Time = 53minutes
Convert 53minutes to hour.
60 minutes = 1 hour
53 minutes = x hour
Cross multiply
X hour x 60 = 53
Xhour = 53/60
X = 0.88 hour
Therefore
Speed = 6.36km /0.88hr
= 7.23km/h
<span>y+2>1/2-2 looks a little strange. Is it OK to combine the last 2 terms?
</span><span>y+2> -3/2
Then y > -2 - 3/2, or y > -7/2. y must be greater than -7/2, greater than -3.5.</span>
