Answer:

y=0.46591x+7.71591

Step-by-step explanation:

Labelled points are (21,\: 17.5)=(x_1,\:y_1) \: \&\:(43,\: 27.75)=(x_2,\:y_2)

Slope of line (m) =\frac{27.75-17.5}{43-21}  =\frac{10.25}{22} =\frac{41}{88}

Equation of line in point - slope form is given as:

y-y_1 = m(x-x_1)

\therefore y-17.5= \frac{41}{88} (x-21)

\therefore y= \frac{41}{88} x-\frac{861}{88}+17.5

\therefore y= \frac{41}{88} x+17.5-\frac{861}{88}

\therefore y= \frac{41}{88} x+\frac{1,540-861}{88}

\therefore y= \frac{41}{88} x+\frac{679}{88}

\therefore y=0.465909091x+7.71590909

\therefore y=0.46591x+7.71591
