Answer:
A line having slope 10 passes through (-8,4)
So,eq of line becomes
y -4 = 10( x+8)
y-4 = 10x +80
y-10x = 84
As (w,-6) lies on a line
So, plugging above point in equation
y-10x=84
-6 -10w = 84
-10w = 90
w = -9
Answer:
w=-9
Step-by-step explanation:
Line D:=10x+b
let’s find b:
A(-8,4)∈D ⇔ 4=10(-8)+b ⇔ b=84
then D:y=10x+84
B(w,-6)∈D ⇔ -6=10w+84 ⇔ -90=10w ⇔ w=-9
