Question

The slope of the line formed by joining the points A(1, 3) and B(4, 7) is .

• A. $\frac{4}{3}$
• B. $\frac{-4}{3}$
• C. $\frac{3}{4}$
• D. $\frac{-3}{4}$

Answer 1

The correct option is A $\frac{4}{3}$

$\mathrm{Slpoe}\mathrm{of}\mathrm{the}\mathrm{line}\mathrm{formed}\mathrm{by}\mathrm{two}\mathrm{points}(x_1,y_1)\mathrm{and}(x_2,y_2)\mathrm{is}\mathrm{given}\mathrm{by}\frac{y_2-y_1}{x_2-x_1}$
$\therefore {\mathrm{Slope}}_{\mathrm{AB}}=\frac{7-3}{4-1}=\frac{4}{3}$
