Question 890169
The standard for of a line is y = mx +b, where b is the y intercept and m is the slope.
m is defined as (y2 - y1) / (x2 - x1) = (-9 -(-7)) / (-6 -(-2)) = -2/-4 = 1/2
so far we have
y = x/2 + b
now we can select a point, say (-2, -7)
-7 = -2/2 +b
b = -7 +1 = -6
the equation for our line is
y = x/2 -6
