Answer:
[tex]y=-\frac{1}{3}x-5[/tex]
Step-by-step explanation:
step 1
Find the slope
The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
we have
[tex]A(-6,-3)\ B(6,-7)[/tex]
Substitute the values
[tex]m=\frac{-7+3}{6+6}[/tex]
[tex]m=\frac{-4}{12}=-\frac{1}{3}[/tex]
step 2
we know that
The equation of the line into slope intercept form is equal to
[tex]y=mx+b[/tex]
we have
[tex]m=-\frac{1}{3}[/tex]
[tex]B(6,-7)[/tex]
substitute and solve for b
[tex]y=mx+b[/tex] ------> [tex]-7=-\frac{1}{3}*6+b[/tex]
[tex]-7=-2+b[/tex]
[tex]b=-5[/tex]
The equation of the line is equal to
[tex]y=-\frac{1}{3}x-5[/tex]
