Can you write this equation in point-slope form?<br><br> y = ½x + 4?
Svet_ta [14]
Yes.  This equation given:
______________________________
   " y = (½)x + 4 " ;  in point-slope form; also known as: "slope-intercept form" ; is:
______________________________________
    " y = (½)x + 4 " .
______________________________________
In other words, the equation given is ALREADY written in "point-slope form" ; or, "slope-intercept form".
______________________________________
Note:   An equation that is written in "point-slope form"
             (or, "slope-intercept form"), is written in the format of:
______________________________________
" y = mx + b " ;_________________
in which:_________________
"y" is a single, "stand-alone" variable on the "left-hand side of the equation"; "m" is the coefficient of "x"; also:
"m" is the slope of the line; which is what we want to solve for;
"b" is the "y-intercept"; or more precisely, the value of "x"
(that is; the "x-coordinate") of the point at which "y = 0";
that is, the value of "x" ; or the "x-coordinate" of the point at which
the graph of the equation crosses the "x-axis".
______________________________________
Note that in our given equation, which is written in "point-slope form" (or, "slope-intercept form" — that is:  " y = mx + b "  ;
_______________________________________
which is:  " y = (½)x + 4 " ;
_______________________________________
we have:
_______________________________________
  "y" isolated as "stand-alone" variable on the "left-hand side" of the equation;

  m = ½ ;
  b =  4 .

V1/V2=T1/T2. Solve for V1
Ahat [919]
V1=(T1/T2)*V2
In this problem, since you are given no actual numbers, the only thing you can do is multiply V2 over to get V1 alone. Since you can't cancel anything out, you are left with the answer above.
