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
