Answer:
Step-by-step explanation:
note : an equation is : y - b = m(x - a) ... the point is : A ( a , b) and slope : m
in this exercice : m= - 8 and a= - 3 and b= -6
an equation is : y+6 = -8(x+3)
you can write : y+6 = - 8x -24
8x+y = - 30 .....answer : C
Answer:
C. 8x + y = -30
Step-by-step explanation:
-6 = -8[-3] + b
24
-30 = b
y = -8x - 30
+8x +8x
