Answer:
12. (4, 7)
13. (5, -1)
Step-by-step explanation:
Rewrite in vertex form and use this form to find the vertex (h, k).
<span>x=1/4y+2</span>
−4x+3y=4-------> substitution method
<span> -4(1/4y+2)+3y=4</span>
-y-8+3y=4-
--------> 2y=4+8- ----->y=6
x=1/4y+2-
-----> ¼(6)+2=7/2
the
answer is (7/2,6)
