Question

Find the equation of a line that passes through the points (2,7) and (4,6). Leave your answer in the form y = m x + c

Answer 1

I think the answer would be

y = 0.5x -8

tough this might be wrong?

Explanation:

(2, 7) ( 4,6)

to find the gradient- mx

y2-y1/ x2 - x1

chose which would be 1/ 2

if I chose (2,7) as 1 then (4, 6) as 2

mx = 6- 7/ 4-2

= -0.5x

y = -0.5x + c

substitute

6 = -0.5(4) + c

6= -2+ c

c = -8
