Answer:
The equation of the new line is 
or 
Step-by-step explanation:
step 1
Find out the slope of the line with x-intercept (3,0) and y intercept (0,3)
The formula to calculate the slope between two points is equal to
substitute the values
step 2
Find the slope of the new line perpendicular to the given line
we know that
If two lines are perpendicular,then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
we have
----> slope of the given line
so
---> slope of the new line
step 3
Find the equation of the new line in point slope form
we have
substitute
----> equation in point slope form
Convert to slope intercept form
isolate the variable y
Answer:
2 hours
Step-by-step explanation:
If she was 5km away and is now 2km away she walked 3 km. To walk 3 km at 1.5 km/h you have to divide 3km by 1.5km to get 2 hours

We have been given the truth table for three variables p, q, and r. as shown below
p q r
A T T T
B T T F
C T F T
D T F F
E F T T
F F T F
G F F T
H F F F
Now we need to find Which statements are true for rows A and E for the following statements:
p ↔ q p ↔ r q ↔ p q ↔ r r ↔ p r ↔ q
To find that we need to use table of P <-> Q as shown in picture.
We know that if both statements are true for P and Q then only P <-> Q will be true. So using that trick we see that only q<->r and r<->q are the final answer as shown in the attached picture.
