From our assumption, our sample size will be 5.

The probability that a subject will solve more than 1 puzzle will be number of occurrence from 2 to 5 which is 4.

What is the equation of a line with a slope of 7 and a point (1, 8) on the line?
Helen [10]

Answer:

y=7x+1

Step-by-step explanation:

we know that

The equation of the line into slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept

In this problem we have

m=7

point(1,8)

substitute and solve for b

8=7(1)+b

8=7+b

b=8-7=1

The equation of the line is equal to

y=7x+1

 Therefore, the answer is the second option shown above, which is:

 <span>the line y = x</span>
 
 Below is a graph where you can see the symmetry of xy = 4 with respect to the oblique axis x = y. This axis cuts the curves just at its apex
