Fine the equation, in standard form, of the line passing through the points (3,-4) and (5,1)

Talja [164]

The point-slope form:

$y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (3, -4) and (5, 1). Substitute:

$m=\dfrac{1-(-4)}{5-3}=\dfrac{5}{2}\\\\y-(-4)=\dfrac{5}{2}(x-3)$

The standard form: $Ax+By=C$

$y+4=\dfrac{5}{2}(x-3)$ multiply both sides by 2

$2y+8=5(x+3)$ use distributive property

$2y+8=5x+15$ subtract 2y from both sides

$8=5x-2y+15$ subtract 15 from both sides

$-7=5x-2y$

<h3>Answer: 5x - 2y = -7</h3>
