Question

Fin the equation of the line whose slope is 3, and passes through point (2,

4). Write it in point-slope.
y + 4 = 3(x - 2)
y - 4 = 3(x + 2)
y - 4 = 3( x - 2)
y-2 = 3(x - 4)

Answer 1

use the point slope formula.. just memorize this formula.. you'll need to so often y-y1 = m(x + x1) and know it's name There is another one that is similar in form and name

Explanation:

M = 3

P1 =(x1, y1 ) = (2,4)

plug it into the point slope formula

y-4 = 3(x+2)

the second choice looks pretty good
