Write the equation of the line in slope-intercept form that has the following points: (2, -1)(5, -3)
kirza4 [7]

Answer:

\large\boxed{y=-\dfrac{2}{3}x+\dfrac{1}{3}}

Step-by-step explanation:

The skope-intercept form:

y=mx+b

m - slope

b - y-intercept

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (2, -1) and (5, -3). Substitute:

m=\dfrac{-3-(-1)}{5-2}=\dfrac{-3+1}{3}=\dfrac{-2}{3}=-\dfrac{2}{3}

We have the equation:

y=-\dfrac{2}{3}x+b

Put the coordinates of the point (2 , -1) to the equation:

-1=-\dfrac{2}{3}(2)+b

-1=-\dfrac{4}{3}+b           <em>add 4/3 to both sides</em>

\dfrac{1}{3}=b\to b=\dfrac{1}{3}

Finally we have:

y=-\dfrac{2}{3}x+\dfrac{1}{3}

n= -3

-2(4+2n) = - 20

-8+4n = -20

4n = -20+8

4n = -12

divide both sides by 4
