Answer:
(-3/4, -7/2)
Step-by-step explanation:
y= −2x − 5
y= 2x − 2
2y = -7
y = -7/2
y= 2x − 2
-7/2 = 2x - 2
2x = -3/2
x = -3/4
(x,y) = (-3/4, -7/2)
a) 1,000 + 0 + 40 + 9
b) 40,000 + 3,000 + 800 + 70 + 0
c) 8,000,000 + 100,000 + 5
We can observe that the function describing the graph is linear and so the equation is of linear nature:

Numbers m and n have special names. m is called the slope, n is called y-intercept.
From the graph one can tell that the line intercepts y-axis at y = -1 that means n = -1. What about the slope you say?
The slope can be calculated using two points' coordinates that lie on the line:

Now our line has an equation,
