A. what is the slope of the graph?

b. write an equation for the line.

Part A) The slope is  

Part B) The equation of the line is

Step-by-step explanation:

Part A) What is the slope of the graph?

we know that

The formula to calculate the slope between two points is equal to

Looking at the graph it takes any two points

(-2,0) and (0,-1)

substitute the values in the formula

Part B) Write an equation for the line

we know that

The equation of the line in slope intercept form is

where

m is the slope

b is the y-coordinate of the y-intercept

we have

----> the y-intercept is the point (0,-1)

substitute
