See below

Explanation:

A polynomial #n# degree in standar form is

#p(x)=a_nx^n+a_(n-1)x^(n-1)+...+a_2x^2+a_1x+a_0#

Which have #n+1# terms (from #a_0# to #a_n#)

In particular case of #5-3x# is a plynomial of two terms and degree #1#. Coefficientes are #-3# (of the first degree) and #5# independent term (or degree zero term because #x^0=1#).

In standard form: #color(blue)(-3x+5)#
Degree: #color(blue)1#
Number of terms: #color(blue)2#

Explanation:

In standard form, the terms of a polynomial are arranged in decreasing degree.

The degree of a polynomial is the largest degree of any of its terms.

The degree of a term is the sum of the exponents on all variables in the term.

Terms of a polynomial are the sub-components of the polynomial connected by to other components by only addition or subtraction.

As originally given:
#{: ("first term:",color(magenta)(5),color(white)("xx"),"degree: "color(magenta)0" (since "5=5x^color(magenta)0")"), ("second term: ",color(magenta)(-3x),,"degree: "color(magenta)1" since "-3x=-3x^color(magenta)0")") :}#

Arranged in decreasing degrees:
#color(white)("XXX")-3x+5#
