Answer:
The slope intercept  of the given line equation AB is [tex]y  = \frac{1}{2}  ( x)- \frac{5}{2}[/tex]
Step-by-step explanation:
Here,the two given point s are A ( -9,-2) and B (1,3).
Now, the slope m of the line AB Â = Â [tex]= \frac{y_2 - y_1}{x_2 -x_1}[/tex]
[tex]\implies m = \frac{3 - (-2)}{1 - (-9)} Â = \frac{3+2}{1+9} Â = \frac{5}{10} Â = \frac{1}{2}[/tex]
or, the slope of line AB = 1/2
Now, the POINT SLOPE FORM of any equation with point (x0,y0) and slope m is given as :
y - y0 = m (x -x0)
So, the line equation of AB is given as :
[tex]y - 3 = \frac{1}{2}  ( x-1)\\\implies y  =3 +  \frac{1}{2}  ( x-1)\\or, y  = \frac{1}{2}  ( x)- \frac{5}{2}[/tex]
SLOPE INTERCEPT form is y = mx + c
Hence, the slope intercept  of the given line equation AB is [tex]y  = \frac{1}{2}  ( x)- \frac{5}{2}[/tex]
