15) y= 1/2 + 3.75

16) y = x

Step-by-step explanation:

For #15)

Equation used: y=mx+b ; Slope: y₂ - y₁ / x₂ - x₁

1) First, you need to pick any 2 points on the graph. I'll use (6,3) and (8,4).

2.1) Then you'll use the slope equation to find the slope (m) of your equation.

(y) ~ 4 - 3 = 1

(x) ~ 8 - 6 = 2

Slope= 1/2

3) So from the look of the answers, the y here is 3.75 so you can trust that.

4) The final equation is y= 1/2 + 3.75

For #16)

Use the same steps as #15. You can still choose whatever points/plots you want. Ima use (5,4) and (6,5).

(y) ~ 4 - 3 = 1

(x) ~ 6 - 5 = 1

slope= 1 or x

y=x

Your welcome for the answer! <3
