equation of this line????

Answer:
y = 1/2 x - 3
Step-by-step explanation:
Equation of line:
y = mx + b
We only need to find m(slope) and b(y-intercept)
We first find the slope of the line
Get any two points from the line.
(4,-1) (2,-2)
m = (y2 - y1) / (x2 - x1)
m = -2 - (-1) / 2 - 4
m = -1 / -2
m = 1/2
Now we find b (slope intercept)
This is easily found by looking where the line and the vertical line(y-axis) met.
The line passes to -3
So now that we have m and b,
y = 1/2x - 3
