Given:
The points are (-3, 2) and (2, -13).
To find:
Slope-intercept form of the equation.
Solution:
Here [tex]x_1=-3, y_1=2, x_2=2, y_2=-13[/tex].
Slope of the line:
[tex]$m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]$m=\frac{-13-2}{2-(-3)}[/tex]
[tex]$m=\frac{-15}{5}[/tex]
m = -3
Using point-slope formula:
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-2=-3(x-(-3))[/tex]
[tex]y-2=-3(x+3)[/tex]
[tex]y-2=-3x-9[/tex]
Add 2 on both sides.
[tex]y-2+2=-3x-9+2[/tex]
[tex]y=-3x-7[/tex]
Slope-intercept form of the equation is y = -3x - 7.
