Answer:
No
Step-by-step explanation:
Perpendicular slopes, when multiplied together, equal negative 1
1/2 *2 = 1 not negative 1
These lines are not perpendicular
Answer:
The lines are not perpendicular
Step-by-step explanation:
m1=1/2
m2=2
m1*m2=1/2*2=1
Lines are perpendicular when m1 * m2 = -1 because m1 * m2 = 1 these lines are not perpendicular

Answer:
x=1 y=7
Step-by-step explanation:
−5x+2y=9
y=7x
Substitute the second equation into the first
-5x +2(7x) = 9
Distribute
-5x +14x = 9
Combine like terms
9x=9
Divide by 9
9x/9 =9/9
x= 1
Now find y
y = 7(1)
y = 7
