Answer:
-3
Explanation:
Point slope means y-y=m(x-x)
m is the slope
in this case, -3 is the slope
y+2=-3(x+1)
2. Use the coordinates of the labeled points to find a point slope equation of this line -5,2 -1,0.
The answer would be (slope-intercept): y=-0.5x-0.5
To find the answer, you'd find the slope from the two points...
y=-0.5x+b
then substitute y and x and add in x and y values from a point (I'll use the point -5,2)
2=-0.5(-5) + b
simplify and isolate to get
b=-0.5
