Answer 1

when two lines are parallel, they have the same slope
equations of a line are written in the form
y=mx+c
y=-3x+12

we see that the slope, or m, is -3
so we have the slope, -3, and point (-1,6), we can now form an equation :)

\[m=\frac{ \Delta y }{ \Delta x }\]

do you know how to do...or i explain further

Answer 2

please explain further @Mokeira

Answer 3

but you get the formula right?

Answer 4

the one on finding m(slope)

Answer 5

@milkbabie

Answer 6

is it y = -3x + 7 @Mokeira

Answer 7

not really
\[m =\frac{ y _{1}-y _{2} }{ x_{1}-x_{1} }\]
\[-3=\frac{ y-6 }{x --1 }\]
cross multiply
-3(x+1)=y-6
simplify that

Answer 8

y = -3x + 3 @Mokeira

Answer 9

correct :)
