Plugging in the values from the two matrices will give us the answer A
Answer: x= -8/3
Step-by-step explanation:
The dlope-intercept form:

m - slope
b - y-intercept (0, b)
The formula of a slope:

We have two points from the graph
x-intercept: (-1, 0)
y-intercept: (0, - 1) → b = -1
Substitute to the formula of a slope:

<h3>Answer: y = -1x - 1 = -x - 1</h3>
Check the picture below.
so the area of the hexagon is really just the area of two isosceles trapezoids.
