Y=mx+b
m=slope
b=y intercept
perpendicuar lines have slopes that multiply to get -1
so
solving for y
add 4x both sides and divide by5 to get
y=4/5x+2
slope is 4/5
perpendicular means the slopes multiply to get -1
so
4/5 times what=-1?
what=-5/4
so
y=(-5/4)x+b
find b
given the point (-15,8)
8=(-5/4)(-15)+b
8=75/4+b
-43/4=b
y=(-5/4)x-43/4
The resulting equation will be , when the expression for y in the second equation is substituted into the first equation.
<h3>Given equations,</h3>
According to the question, When the expression for y in the second equation is substituted into the first equation it means we have to put the value of from equation (2) in equation (1).
<h3>Resulting Equation,</h3>
Hence the required equation is . So the correct option is (A) .

Answer:
8) 1/3, 0.33, 33 1/3%
9) 2/3, 0.67, 66 2/3%
Step-by-step explanation:
Answer B shows the correct information. If you look at the totals of the tables, B shows that 30 aren't in a band, 20 are in a band, and 25 play an instrument.
The answer is 72 because 2x6=12 and 5x12=60 and together it’s 72
