Answer:
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Where m = slope of the line
b = y-intercept
Slope of the line 'm' = -
y-intercept 'b' of the line is equal to the y-intercept of another line given as,
Here y-intercept of the line 'b' = -2
Therefore, the equation of the line will be,
y = (-)x + (-2)
Here negative slope represents a line which is decreasing having y-intercept = -2
Therefore, last graph (bottom) given in the picture will be the answer.
