Answer:
Step-by-step explanation:
THe standard form of equation of a line is expressed as y = mx+c
m is the slope of the line
c is the y-intercept
Using the coordinate from the graph (-4, 0) and (0, -4)
m = y2-y1/x2-x1
m = -4-0/0-(-4)
m = -4/4
m = -1
The y intercept is the point where the line cuts the y axis
The point where the line cuts the y axis is at y = -4
Hence c = -4
Get the required equation
y = mx+c
y = -x - 4
y + x = -4
