Answers
Answer:
A
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 5, 5) ← 2 points on the line
m = [tex]\frac{5-0}{-5-0}[/tex] = [tex]\frac{5}{-5}[/tex] = - 1 → A

A function is a relationship between inputs where each input is related to exactly one output.
f(1) = 97
f(2) = 194
f(3) = 291
Where f(x) is the calories burned.
x is the number of miles walked.
Yes, the given relation in the table is a function.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Function:
Miles walk = input
Calories burned = output
We know that,
A function can have many-to-one and one-to-one.
A function can not have one-to-many.
Now,
From the table,
f(1) = 97
f(2) = 194
f(3) = 291
We see that the relation is a function.
The relation is a one-to-one relation.
Thus,
The given relation in the table is a function.

The equation of a line in point-slope form with slope 1/4 and point (4, 2)
is y - 2 = (1/4)(x - 4).
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
The equation of a line is point-slope form is y - y₁ = m(x - x₁).
Given, Slope is 1/4 and has point (x₁, y₁) = (4, 2).
∴ The equation of the given line is y - 2 = (1/4)(x - 4).
