Let
x------> height of Leon's older brother
y------> height of Leon
Convert mixed number to an improper fraction

we know that
-----> equation A
-----> equation B
substitute equation A in equation B

Convert to mixed number

therefore
<u>the answer is</u>

Slope intercept form is y=mx+b because m=slope and b=y-intercept hence "slope intercept form"...
m=deltay/deltax=(0-5)/(-9--6)=-5/-3=5/3 so far we have now:
y=5x/3 +b, using any point, I'll use (-9,0) we can now solve for b or the y-intercept...
0=-9(5)/3 +b
0=-15+b, so b=15 and our line is:
y=5x/3 + 15 or more neatly
y=(5x+45)/3
1. Y=4
2. Y=2
3. Y=X
4. Y=2
(X,Y)
