Answer:
y = (4/3)x - 50
Step-by-step explanation:
Step 1 :
Identify the independent and dependent variables.
The independent variable (x) is the square footage of floor space.
The dependent variable (y) is the monthly rent.
Step 2 :
Write the information given in the problem as ordered pairs.
The rent for 600 square feet of floor space is $750 :
(600, 750)
The rent for 900 square feet of floor space is $1150 :
(900, 1150)
Step 3 :
Find the slope.
m = (y₂ - y₁) / (x₂ - x₁)
Substitute (600, 750) for (x₁, y₁) and (900, 1150) for (x₂, y₂).
m = (1150 - 750) / (900 - 600)
m = 400 / 300
m = 4/3
Step 4 :
Find the y-intercept.
Use the slope 4/3 and one of the ordered pairs (600, 750).
Slope-intercept form :
y = mx + b
Plug m = 4/3, x = 600 and y = 750.
750 = (4/3)(600) + b
750 = (4)(200) + b
750 = 800 + b
-50 = b
Step 5 :
Substitute the slope and y-intercept.
Slope-intercept form
y = mx + b
Plug m = 4/3 and b = -50
y = (4/3)x + (-50)
y = (4/3)x - 50
The answer is A. because the side lengths of the shape doesn't change. The side lengths are still 3 and 5.
Hope this helps!

Answer:
x = 9
Step-by-step explanation:
6 × 9 = 54
54 + 15 = 69, which is less than 70.
In y=mx+b, m= slope and b= y-intercept. All you have to do is substitute.

A time-series plot is a graphical representation in which the measure of time is expressed on the x-axis and what is to be measured is represented on the y-axis.
A time-series plot also known as a line chart helps to depict data from any event that has been gathered in a time sequence.
- It is usually represented on a graph where the measure of time is expressed on the x-axis and what is to be measured is represented on the y-axis. It is also used for the visualization of trends and patterns. e.g seasonal changes in climate.
