Find the equation of the straight line passing through the points (-3,4) and (8,1)

Answers

Gradient =

$\frac{y-y_1}{x-x_1}$

=

$\frac{1-4}{8-(-3)}$ =

$\frac{-3}{11}$

Pick one of the points equation is

$\frac{y-1}{x-8}$ =

$\frac{-3}{11}$

11y - 11 = -3x + 24

11y + 3x = 35

y =

$\frac{-3}{11}x$ +

$\frac{35}{11}$
