Question

Write an equation in point-slope form of the line through point J(4, 2) with slope 3.

Answer 1

strate line thru point=(4,2) with slope=3...

y=3x+konst

projekt line from (4,2) bak tu x=0...deltax=-4, deltay=slope*dektax=-12

y at x=0...2-12=-10

y=3x-10

Answer 2

muneepenee is absolutely correct, y = 3x -10
