Find the slope of the line

A. 2
B. -2
C. 1/2
D. -1/2

B. -2

Step-by-step explanation:

As this is the straight line, so that the equation the line represents has the following form:  Y = f(X) = a.X + b

=> a is the slope of the line

Looking at the graph, we can see that the line crosses two points: A(2;0) and B(0;4).

A (2;0) =>

B (0;4) =>

So that we have:

+)

=> 0 = a.2 + b => b = - 2a (1)

+)

=> 4 = a.0 + b => b = 4

Replace b = 4 into (1)

=> 4 = -2. a => a = 4 / (-2) = -2

So a = - 2 => Slope of the line is -2

the answer is b i just did that
