y = 3x + 9
0 = 3x + 9 -y
3x - y + 9 = 0 (standard form)
Reasons : maths equations is firstly write down from a to z and last is write down numbers.

a million) The parallel equation may well be written as y=3x-8, for that reason 3 is the slope for this and your line. there's a equation for a line referred to as ingredient slope written as y-b=m(x-a) the place (a,b) is a ingredient on the line and m is slope. for that reason the line could be y-2=3(x-7). This simplifies to y=3x-19 or 3x-y=19 2) the line given is y=2x-7, for that reason 2 is the slope. despite the fact that your slope is perpendicular to this, or the destructive inverse of two: -a million/2. you have a ingredient lower back, so the equation is y-5= (-a million/2)(x-8). This simplifies to y= -x/2+9 or x+2y=18

Use the formula Ax+By+C=0
y=3x+9
y-9=3x
3x-y+9=0
So your answer is 3x-y+9=0.
