Answer:
k = 5,
y = 5x
Step-by-step explanation:
If y is proportional to x,
y ∝ x
Then the equation will be
y = kx
Her k = proportionality constant.
Now we choose a point from the given table.
Let the point is (2, 10).
By putting the values of x and y in the equation,
10 = 2×k
k = 
k = 5
This will be true for any point we choose from the table.
And the equation will be y = 5x
Answer:
Conversion and substitution
Step-by-step explanation:
One way to find out if the expression is true, we can convert all the percentages into their decimal equivalence.
60% = 0.6
10% = 0.1
6% = 0.06
Now let's substitute the values.
0.06 = 0.6 x 0.1
0.06 = 0.06
Since 0.06 is equal 0.06, this then proves that it is true.
Answer:
0
Step-by-step explanation:
No matter what value of x you input into this equation, you will get a y value of 3. This means that over infinite run, the line has no rise, and therefore has slope of 0. Hope this helps!
