Answer:
A proportional relationship is something like:
y = k*x
Where k is the constant of proportionality
And a linear relationship is something like:
y = a*x + b
Is easy to see that if:
a = k, and b = 0, this would be a proportional relationship.
Then if we want to have a slope equal to 3, but this must not be a proportional relationship, we must only have b different than 0.
This could be something like:
y = 3*x + 1
The graph of this is:

Hello!
If s(x) = x - 7 and t(x) = 4² - x + 3, find (t · s)(x) is also known as a composite function. (t · s)(x) is read as "t is composed of s", or "the composition of t and s".
(t · s)(x) = 4² -(x - 7) + 3
(t · s)(x) = 16 - x + 7 + 3
(t · s)(x) = -x + 16 + 7 + 3
(t · s)(x) = -x + 26
Therefore, (t · s)(x) = -x + 26.
Real life problem for quadratic equation:
A ball is thrown into the air from the edge of a building, 50 feet above ground. It’s initial velocity is 20 feet per second. About how long does it take for the ball to hit the ground?
Sorry if this doesn’t help.
