1. find equation
general solutions are:
for P(0,-11)
⇒
for p(1,-13)
and
solve for a and b:
the total equation is now:
To find the x-intercept set y=0 and solve for x
Answer:
see explanation
Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is
= 
( substitute in values )
= 
( cross- multiply )
12(x - 1) = 72 ( divide both sides by 12 )
x - 1 = 6 ( add 1 to both sides )
x = 7

The parallel line segment SV is half of RW
that is x = 7.5
SV also divides the sides RT and WT in proportion, that is
= 
( cross- multiply )
10y = 24 ( divide both sides by 10 )
y = 2.4
Answer:
b
Step-by-step explanation:
just only do B
where x=0, y=2
