Answer:
.
Step-by-step explanation:
Start by finding the slope of the line perpendicular to 
.
The slope of is 
.
In a plane, if two lines are perpendicular to one another, the product of their slopes would be 
.
Let 
denote the slope of the line perpendicular to . The expression 
would denote the product of the slopes of these two lines.
Since these two lines are perpendicular to one another, 
. Solve for : 
.
The 
is a point on the requested line. (That is, 
and 
.) The slope of that line is found to be . The equation of that line in the point-slope form would be:
.
Rewrite this point-slope form equation into the slope-intercept form:
.

Answer:
Correct
Step-by-step explanation:
S - the number of the t-shirts;
h - the number of hats:
The system of equations:
s + h = 23
10 s + 12 h = 246
--------------------------
s = 23 - h
10 * ( 23 - h ) + 12 h = 246
230 - 10 h + 12 h = 246
2 h = 246 - 230
2 h = 16
h = 16 : 2
h = 8
s = 23 - 8
s = 15
Answer: The basketball team sold 15 t-shirts and 8 hats.
