is this a maths attempt? heh heh.. a million & 2. (y1 - y2)/(x1 - x2) 3. Use the above formulation to get the gradient and see which of them are the comparable. those are the parallel strains. 4. Rearrange the equation so as that that is comparable to x (x=3y +15). because ur looking 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 distinctive, the fabricated from their gradient might ascertain to -a million. you may 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 searching for is perpendicular to the 2nd eq, their product might effect in -a million. Insert the gradient and the intercept into the gradient variety. 8. I'v 4gotten bout applications... sorry.. 9. by utilising now u could be waiting to respond to this. 10. And this too.. satisfied attempting! =P

what's d?
i think b and c
cause m=3
and perpendicular gonna be -1/3
and vice versa

its b and c
gradient of c multiplied by gradient of b = -1
wheres (d) by the way?
