Question 243341: Find and equation of the line containing the given pair of points
(-7,-2)and (-1,-3)
The equation of the line in slope-intercept form is y=?
Simplify your answer.
Can anyone please help me I'm going crazy trying to find the answer. Thanks

The line formula is:
Y=mX+b where m=slope & b=the Y intercept.
(-7,-2)and (-1,-3)
Slope=(y2-y1)/(x2-x1)=(-3+2)/(-1+7)=-1/6 for the slope.
Now replace X & Y in the line formula & solve for b the Y intercept.
-2=-1/6*-7+b
-2=7/6+b
b=-2-7/6
b=-12/6-7/6
b=-19/6 this is the Y intercept.
y=-x/6-19/6
