Answer:
m < 0, b < 0
Explanation:
The equation of a straight line graph can be represented by;
y = mx + b
where m is the slope and b is the y-intercept
As we can see, we have an intercept on the negative y axis
What this mean is that the value of b is less than zero
For the slope, what we have is a falling graph
Whenever a graph is falling from left to right, it shows that the rate of change between the variables is negative. Accordingly, we can confirm that the value of the slope is less than zero
