Answer:
Slope is -1
Step-by-step explanation:
We have that the equation of a line is:
y = m + bx
where, m is the slope, but to know the slope we have a formula that is:
m = (y2 - y1) / (x2 - x1)
We have 3 points of the line:
(-8,6); (-2,0); (0,-2)
When we want to know the slope we need two points and they can be any two points in any order, so we can say we are going to use:
Point 1:
(-8,6)
Point 2:
(-2,0)
y1 = 6; y2 = 0
x1 = -8; x2 = -2
Now we substitute the values in the formula for m:
m = (0-6) / (-2+8)
Now we solve:
m = -6/6
m = -1, This is the slope.
