Ineed q: find the slope for each line rise-3,run4

They are basically giving you the answer.

Remember, Slope= Rise over Run!

So If your rise is 3 and your run is 4, your slope would then be 3/4!

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
