No, she is incorrect (in my opinion) i think the answer is :
1/2 m - 4 = 5
4+5 = 9 so
half of 18= 9
so the answer is 18?
-3x-6y=17
-6y=3x+17
y=-x/2-17/6 so the slope of the line is -1/2
For another line to be perpendicular to this one the product of their slopes must equal -1
(-1/2)m=-1, m=2 so the perpendicular line will have a slope of 2...
y=2x+b, using point (6,3) we can solve for b...
3=2(6)+b
3=12+b
b=-9 so
y=2x-9
Answer:
see explanation
Step-by-step explanation:
step 4 take the square root of both sides
= ± 
x + 4 = ± 
step 5 subtract 4 from both sides
x = - 4 ± 
step 6 solve for x
x = - 4 -
or x = - 4 +
