Answer:
undefined slope
Step-by-step explanation:
The points contain the same x-value. This means that the line is vertical.
All vertical lines have an undefined slope.
Hope this helps.
Linear functions have to have the same slope between any 2 points
find the slope betwen them
slope betwen 2 points (x1,y1) and (x2,y2) is
(y1-y1)/(x2-x1)
given
(1,12) and (3,9)
slope=(9-12)/(3-1)=-3/2
if we wanted to chek furthere, we check (3,9) and (5,6) and fnd that the slope is also -3/2
so
y=mx+b
m=slope
b=yint
y=-3/2x+b
find b
if x=1 then y=12
12=-3/2+b
add 3/2 both sides
12+3/2=b
13+1/2=b
26/2+1/2=b
27/2=b
y=-3/2x+27/2
try them
we have 2 x values
7 and 3
input them and see their outputs
for x=7
y=-3/2(7)+27/2
y=-21/2+27/2
y=6/2
y=3
(7,3) is a valid point
for x=3
hold a second, we already have a x=3
it is (3,9)
none of them
answer is (7,3)
En matemáticas, un conjunto contable es un conjunto con la misma cardinalidad (número de elementos) que un subconjunto del conjunto de números naturales. Un conjunto contable es un conjunto finito o un conjunto contable infinito.
Answer:
-10 feet below the surface of the water
Step-by-step explanation:
We are told that the dive rings position at the bottom of the pool is 10 feet below the surface of the water.
Now, an integer is basically a whole number that can either be be zero, positive or negative.
In this case, it's below the surface which means it's below zero.
Thus, it's negative.
So the integer is -10 feet below the water surface.
