Question

consider the line L with equation y+2x=3. The line L(sub 1) is parallel to L and passes through the point (6,-4). A) find the gradient of L(sub 1). B) Find the equation of L(sub 1) in the form y=mx+b. C) Find the x-coordinate of the point where line L(sub 1) crosses the x=axis.

Answer 1

Hello,

$a)L:y=-2x+3\ slope\ or\ gradient=-2\\ b) L_1: y+4=-2(x-6)==\ \textgreater \ y=-2x+8\\ c) y=0=-2x+8==\textgreater\ x=4$
