Answer:
6.
Step-by-step explanation:
Proportional triangles once again:
24/8=18/x
18*8=144
144/24=6
:)
M=(y2-y1)/(x2-x1) <em>(Multiplied terms on both sides of equation by (x2-x1).)</em>
m(x2-x1)=y2-y1 <em>(Added y1 to both sides of equation, ultimately isolating y2.)</em>
y2=m(x2-x1)+y1
Check the picture below.
bearing in mind the a solution is where both graphs intersect.
Zero property because you are using zeros to multiply
