madreJ [45]

15 x .42= $ 6.30 Flour
8 x 3.99 = $31.92 Utter
1 x .67 = .67 Salt
30 x 1.49 = $ 44.70 Apples

Total = $83.59
Dollar amount is $83
Change amount is .59

A line passes through the points (2, –2) and (–6, 2). The point (a, –4) is also on the line. What is the value of a?

leonid [27]

Answer:

The value of a=6[/tex]

Step-by-step explanation:

step 1:-

col linearity of three points :-

We know that slopes of two parallel lines are equal.If two lines having the same slope pass through a common point ,then two lines will coincide . Hence ,If A,B,C are three points in the X Y- plane, then they will lie on a line,

that is three points are col linear if and only if Slope of AB= slope of BC

step 2:-

Since the given three points are col-linear, we have

Slope of AB= slope of BC

given points are A(2,-2) ,B(-6,2) and C(a,-4)

Step 3 :-

Slope of AB= slope of BC

$\frac{2-(-2)}{-6-2} =\frac{-4-2}{a+6}$

$\frac{-1}{2} =\frac{-6}{a+6} by cross multiplication we get \\a+6=12\\Step 4:-The value of a=6$
