Answer:

See below

Step-by-step explanation:

Taking the readings from the graph

  • x ....  y
  • 0 .... 2
  • 2 .... 6
  • 4 .... 10
  • 6 .... 14

Rate of change for the given line is:

  • (6 - 2)/2 = 4/2 = 2
  • y- intercept is 2

Equation for the line is:

  • y = 2x + 2

For the point (40, 76) we can verify with the equation:

  • 40*2 + 2 = 82

The point (40, 76) is close the line but the line doesn't pass through it.

Answer:

x | y

0 | 2

2 | 6

4 | 10

6 | 14

Equation of the line is

[tex] \frac{y - 2}{x - 0} = \frac{6 - 2}{2 - 0} \\ \frac{y - 2}{x} = \frac{4}{2} = 2 \\ y - 2 = 2x \\ y - 2x = 2\\ \boxed{y=2x+2}[/tex]

When x=40, y will be (2×40)+2 =82

So the point should pass through (40,82) and not (40,76).
