Drawing a graph and plotting the points gives B as the location desired.
Answer:
Slope = -4
Step-by-step explanation:
The slope is negative because the line is going down.
The line goes down 4 times and goes right once = 4
Answer:
x= - 30
Step-by-step explanation:
x-9=0.7x+0.6
x-9=1.3x
x-9-1.3x=0
x-1.3x=9
x(1-1.3)=9
-0.3x=9
x= - 9/0.3
x= - 30
Answer:
y=1/2x-3
Step-by-step explanation:
1) Find slope... (y2-y1)/x2-x1–> (-4-(-1))/-2-4=-3/-6=1/2
2) Pick a coordinate and plug into equation y-y1=m(x-x1)—> y-(-1)=1/2(x-4)
3) Simplify to make y alone —> y=1/2x-3
