Hello,
The line passes through (-1,3) and (9,11)
slope=(11-3)/(9+1)=8/10=4/5
y-3=4/5(x+1)
==>y=4/5 *x +19/5
Answer:
<h2>b) 4,5,15</h2><h2 />
Step-by-step explanation:
In a triangle of sides‘s length a , b and c
in order to be able to form (construct) this triangle we must have :
c - a < b < c + a
in fact this work with cases a) ,c) and d)
but not b)
because 15 - 4 is not < to 5
in other words 15 - 4 > 5
You have to use a proportion.
3.5/18= 1.5/x
3.5x=27
x= 7.7 cm
