What is the equation of the line whose y-intercept is 3 and slope is 1?

Answers

Answer:  " y = x + 3 " .
___________________________
Explanation:
___________________________
Consider the equation of a line, in "slope-intercept form" ;

which is:  " y = mx + b"  ;

in which:  "m" refers to the "slope of the line", which is the coefficient of "x".
                "b"  refers to the "y-intercept" of the line", which is given as "3" ; which is the coordinate of "x" of the point at which "y = 0".
_________________________________________________
  So, we can plug in our given values for "m" and "b" into the equation, and write the equation:
_________________________________________________
                   y = 1x + 3 . 
_________________________________________________
            By convention, we can write the "1x" as simply "x" ;  since there is an "implied coefficient" of "1" ;  and an ["implied"] slope, "m", of "1" ; since any value, multiplied by "1", results in that exact same number.  So we can write the equation as:
________________________________________
                 " y = x + 3 " .

y=x+3

Find the value of the expression 74.9+5.23-81.4-16

Answers

Answer:

To find the value of this expression you need to add and subtract from left to right

74.9+5.23-81.4-16 (add the first two, first)

80.13-81.4-16 (74.9+5.23=80.13) (next subtract the next two)

-1.27-16 (80.13-81.4=-1.27) (Last subtract the last two)

-17.27 (-1.27-16=-17.27)

-17.27
