Answer:
x=9
Step-by-step explanation:
Using elimination method.
Add equation 1 to equation 2
x + y = 11
x - y = 7
---------------
2x + 0 = 18
Divide both sides by 2
2x = 18
---- ----
2 2
x = 9
keeping in mind that vertical angles are always congruent.
Answer:
slope= 3/5 y int=-2 equation y = 3/5 -2
Step-by-step explanation:
slope= rise over run
y int = where the y axis and the line meet
equation= y =mx+b
m=slope
b = y int
