Can someone me figure out how to find b in these equations for perpendicular lines also it's do tomorrow so it would really if i got a answer tonight you
a: y=-2x-3
b: y=2x-3
c: y=2x-4
d: y=-2x-2

To find b you would be using the equation y=mx+b so to find be simply look at your equation and put your numbers in place so the answers so you would put your answers for the first one y=(m=-2)x(b=-3)
so easily the answers to these would be a=-3, b=-3 ,c=-4 ,d=-2 
have a good night but definitly remeber the formula i told you for a test 

The answer is
