Hope it helps
The correct answer is 46.38
Slope of line perpendicular to ax+by=c is b/a
given
-2x-8y=18
slope of perpendicular is -8/-2=4
y=4x+b
find B
(4,5)
x=4,y=5
5=4(5)+b
5=20+b
minus 20
-15=b
y=4x-15
Answer:
Step-by-step explanation:
F (-2)=8-4×-4=+16
f(x)=8 so 8 =8-4x so x=0
it is liner algebra . I will send you the graph and every thing later . like in 5 min .
