Answer:
y= -a*x + 12
<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>b</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>b</u>
Step-by-step explanation:
ax+by=12 (subtract "ax" from both sides so that the one on the left will become zero and we will have "by" )
by= -ax+12(divide both side by "by" so that we will have the equation as "y=mx+b")
finally the result will be:
y= -a*x + 12

Answer:
(6,6)
Step-by-step explanation:
To find the x coordinate of the midpoint take the average of the x coordinates of the endpoints
(10+2)/2 = 12/2 = 6
To find the y coordinate of the midpoint take the average of the y coordinates of the endpoints
(3+9)/2 = 12/2 = 6
(6,6)
