Answer:

\huge \boxed{ \boxed{ \frac{2}{3} }}

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\

From the question we have

m =  \frac{3 - 1}{4 - 1}  =  \frac{2}{3}  \\

We have the final answer as

\frac{2}{3}  \\

Hope this helps you

The probability that of testing negative is 0.9 because the probability of testing positive is 0.1

P( at least one) = 1 - P(none) = 1 - (0.93^3) = 0.271
