Step-by-step explanation:
y = ax + b => ax +b = y
-5= a.1+ b => a + b = -5
-9= a.2+b => 2a+b = -9
________-
-a = 4
=> a = -4
a+b=-5 => b = -5 -a
b = -5+4 = -1
so, the Equation : y = -4x -1
All of them except D have no real solutions
Answer:
y=2x-8
Step-by-step explanation:
y-y1=m(x-x1)
y-8=2(x-8)
y-8=2x-16
y=2x-16+8
y=2x-8
