The relation is a function
Hi there! :)
Answer:
Given the information, we can write an equation in slope-intercept form
(y = mx + b) to graph the line:
Plug in the slope for 'm', the y-coordinate of the point given for 'y', and the
x-coordinate given for 'x':
-4 = -2/3(-7) + b
-4 = 14/3 + b
Solve for b:
-12/3 = 14/3 + b
-12/3 - 14/3 = b
-26/3 = b
Therefore, the equation of the line is y = -2/3x - 26/3 (Graphed below)
Some points on the line include:
(-7, -4)
(-4, -6)
(0, -26/3)
(2, -10)
(5, -12)
Answer:
(-3,7)
Step-by-step explanation:
The number of tiles Lynn needs to cover the floor with an area of 16.875 ft² is 17 tiles
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
The floor measures 4 1/2 ft by 3 3/4 ft.
Hence:
Area of floor = 4 1/2 ft * 3 3/4 ft = 9/2 ft * 15/4 ft = 16.875 ft²
Each tile measures 1 square foot each, hence:
number of tiles needed = 16.875 ft² / 1 ft² per tile = 16.875 tiles ≅ 17 tiles
The number of tiles Lynn needs to cover the floor with an area of 16.875 ft² is 17 tiles
