Answer:
0.111111111
Step-by-step explanation:
Answer:<span>x=<span><span><span>23</span>y</span>+<span><span>−11</span><span>3
Or if you need it for a graph question then:
</span></span></span></span><span>
Slope = 3.000/2.000 = 1.500
x-intercept = 11/-3 = -3.66667<span>
y-intercept = 11/2 = 5.50000
I hope this helps.</span></span>
See Below
First, put them into y = mx + b form. From there you can graph them by identifying their slopes and y-intercepts.
