Question

For the following pairs of (x, y) Co-ordinate points, find the linear equation: y=a+bx,
(0,0), (12, 6).
a) x+y = 2
b) x- y = 1/2
( c) y = 1/2x
d) none of these​

Answer 1

Answer:

c)y=1/2x

Step-by-step explanation:

both (0,0) and (12,6) satisfy c)

0=1/2(0)

6=1/2(12)=6

Answer 2

Answer:

y = x/2

Step-by-step explanation:

using equation of a straight line when 2 points are given

$y - y1 \div (y2 - y1) = x - x1 \div (x2 - x1) \\ y - 6 \div (0 - 6) = x - 12 \div (0 - 12) \\ y - 6 \div (- 6 )= x - 12 \div ( - 12) \\ \\ 2y - 12 = x - 12 \\ \\ 2y = x \\ \\ y = x \div 2$
