Find k given that these three points are collinear.<br> A(0, -2), B(2, 0), and C(5, k)

goldfiish [28.3K]

Answer:

k = 3.

Step-by-step explanation:

If they are collinear the slope of AB = the slope of BC, so :-

(0- (-2)) / (2 - 0) = (k - 0) / (5 - 2)

2/2 = k/3

1 = k/3

k = 3.

Solve the system by the elimination method. Check your work. 2a + 3b = 6 5a + 2b - 4 = 0

Lyrx [107]

Solve the system by the elimination method.
2a + 3b = 6
5a + 2b - 4 = 0

multiply thru the top equation by 2
Multiply thru the bottom equation by 3

4a + 6b = 12
15a+ 6b = 12

Subtract and solve for "a":
11a = 0
a = 0

Solve for "b" using 2a + 3b = 6
2*0 + 3b = 6
b = 2
