1 and 2 because when you simplify both of them, 1 and 2 have the same slope, which makes them parralel.

is this a maths attempt? heh heh.. a million & 2. (y1 - y2)/(x1 - x2) 3. Use the above formulation to get the gradient and notice which of them are the comparable. those are the parallel strains. 4. Rearrange the equation so as that this is comparable to x (x=3y +15). because of the fact that ur finding 4 the y-int, x is comparable to 0, meaning, 0=3y+15. remedy it. 5.discover the gradient of each and every of the equation utilising the formulation in no a million. while a line is perpendicular to a various, the manufactured from their gradient would come to a decision to -a million. you could remedy it then. 6. discover the gradient first. Write the equation utilising the gradient variety (y=mx + c; the place m is the gradient). discover the x-int and you'v have been given it. 7. discover the gradient of the 2nd eq. because of the fact the eq ur finding for is perpendicular to the 2nd eq, their product would consequence in -a million. Insert the gradient and the intercept into the gradient variety. 8. I'v 4gotten bout purposes... sorry.. 9. by utilising now u must be waiting to respond to this. 10. And this too.. chuffed attempting! =P

Two points cannot be parallel. I think you mean lines, not points.
If so, lines 1 and 2 are parallel because they both have a slope of -3/5 and they have different y-intercepts.

The first and the second one (y1/x1=y2/x2)
