Answer 1

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:

$y-y_1 = m(x-x_1)$

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

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

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

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

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

$\therefore y=0.465909091x+7.71590909$

$\therefore y=0.46591x+7.71591$
