Line up the equations and add them up, adding the x's together then y's (which should cancel out) then the totals.
Then the equation should equal -9x=36 and when tou solve x= -4.
Plug -4 in for x in one of the equations, I chose the second one, and solve.
y = -21
Hope this helps! :)

Step-by-step explanation:
All three sides are congruent.
Answer:
The given function is
Notice that this function is linear, that means its graph is a straight line.
To graph a linear funtion you just need to use two coordinates.
For
For
So, the points you need are and .
The image attached shows the graph of the given function, where you can observe the two ponints we used.
-1 17/20 and -1 8/10 can be compared easily if we give them common denominators. If we multiply the second fraction by 2, both fractions will have a denominator of 20.
8 * 2 = 16
10 * 2 = 20
New fraction: 16/20
-1 17/20 vs. - 1 16/20
-1 16/20 (-1 8/10) is greater. (For negative numbers, you can tell which one is greater by determining which one is closest to zero.)
