If I randomly choose a person and they test positive, what is the probability that they actually have the disease? Express your answer as a common fraction.

Which equation does the graph below represent?
Sergeu [11.5K]

Answer:

y = (½)x

Step-by-step explanation:

(-8,-4) (0,0) and (8,4)

Use any 2 points to find the slope, hence the equation

slope = (y2-y1)/(x2-x1)

= (0-(-4))/(0-(-8))

= 4/8

= ½

y = (½)x + c

When x=0, y=0

0 = (½)(0) + c

c = 0

Equation is:

y = (½)x
