Question

Write the slope-intercept form of the equation of the line which passes through the points (1, 6) and (2, 9)

Answer 1

slope m=y2-y1.x2-x1=9-6/2-1=3
y-6=3(x-1)
y-6=3x-3
y=3x+3

Answer 2

slope = (9-6)/2-1) = 3
use the general form
y-y1 = m(x-x1)
where m = slope = 3, and (x1, y1) is say (1,6)
so
y - 6 = 3(x - 1)
y = 3x - 3 + 6
y = 3x + 3

Answer 3

lol - i don't why i bother when sai1234 is around - he's like lightning

Answer 4

do you follow that ok john?

Answer 5

(1,6) (x1, y1)
(2,9) ( x2, y2)

M(slope) = y2- y1/ x2-x1

                  = 9-6/ 2-1

                =3

Equation in intercept form is y- y1 = m ( x-x1)

Substituting we get

y- 6 = 3 ( x-1)
y= 3x+3
