Which of the following best describes the function y=5x? It is linear and grows by constant amounts over constant intervals.
It is linear and grows by constant factors over constant intervals.
It is non-linear and grows by constant amounts over constant intervals.
It is non-linear and grows by constant factors over constant intervals.

A. - It is linear and grows by constant amounts over constant intervals.

Step-by-step explanation:

Because x is not in the denominator and x isn't squared, the function is linear. I hope this response helps and is correct!

b, i believe, but not sure.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
