Answer:
y = 2x + 1.5
Explanation:
You can find two points and derive an equation.
Two obvious points are (0, 1.5) and (2, 5.5).
Using the form y = mx + b, you can find the slope m by using the formula
.
m = (1.5-5.5)/(0-2) = -4/-2 = 2.
You can find b by plugging in your m value and one of the two points.
y = 2x + b
1.5 = 2*0 + b
b = 1.5
Thus, your equation is y = 2x + 1.5.
