Step-by-step explanation:
Use formula to find the slope/gradient

(-5, -1) = (x1, y1)
(5, 11) = (x2, y2)
So,

Answer:
Answer B.
Step-by-step explanation:
x+2y=10
2x+8y=16
x=-2y+10
2x+8y=16
2(-2y+10)+8y=16
-4y+20+8y=16
4y=-4
y=-1
x=-2y+10
x=-2(-1)+10
x=2+10
x=12

Step-by-step explanation:
with $4,000 invested, Jake has
8% × $4,000 = $320 annually.
