Answer:
the slope is -4.
Step-by-step explanation:
To find the slope, look at the number in front of the x which is known as the coefficient. Hope this helps :)
7/5 = 14/10 = 28/20
Numerator = x
Denominator = x-4
Add 3 to both:
x +3 / (x-4+3)
x+3 = 14
(x-4 +3) = 10 = x-1 = 10
x = 11
Check:
11 -4 = 7 ( denominator is 4 less than the numerator.)
add 3 to both:
11+3 = 14
7+3 = 10
14/10 reduces to 7/5
The original fraction would be 11/7
Example:
Proportionality=1
5=5x
Divide both sides by 5 , and you get 1=x,
so the proportionality is 1
Answer:
the equation of the line is:
y=-2x+-3
The first one I think because a linear function is always going to have a constant rate of change in one direction going straight up
