So the total for dogs (bottom left box) is 47
17 of them had a cat so the top left box is 17
47-17=30 so 30 have a dog but no cat (left column, middle row)
24 cat but no dog (middle column, top row)
9 no cat no dog (very middle box)
Total no dog= 24 + 9 = 33
Total cat (top right) = 17 + 24 = 41
Total no cat (right column, middle row) = 9 + 30 = 39
Hope this make sense :)

Write an equation of a line containing (2, 1) and (3, 4) in point-slope form.

ivann1987 [24]

Answer:

$y-1=3(x-2)$

$y-4=3(x-3)$

Step-by-step explanation:

The slope formula is given by:

$m=\frac{y_2-y_1}{x_2-x_1}$

The line containing (2, 1) and (3, 4) has slope;

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

The point-slope form is given by:

$y-y_1=m(x-x_1)$

We substitute the point and slope to get:

$y-1=3(x-2)$

$y-4=3(x-3)$
