Find the equation of the linear function represented by the table below in slope-intercept form. x y -1 3 1 1 3 -1 5 -3

Darya [45]

Answer:

y = - x + 2

Step-by-step explanation:

Points given:

(-1, 3), (1, 1), (3, -1), (5, -3)

Slope-intercept form:

y = mx + b

Finding the slope using slope formula and the first two points:

m = (1 - 3)/(1 - (-1)) = -2 / 2 = -1

Finding y-intercept using the slope and the first point:

3 = (-1)*(-1) + b
3 = 1 + b
b = 3 - 1
b = 2

So the equation is:

y = - x + 2

Peterson will need 39 more tiles to completely cover the kitchen floor

Step-by-step explanation:

Given dimensions of kitchen are:

12 feet and 7 feet

In order to find the number of tiles for the kitchen, we have to first find the area of the kitchen

So,

Area of kitchen:

$A = 12 * 7\\ = 84\ square\ feet$

The area is 84 square feet which means 84 one square foot tiles are needed to completely cover the floor of kitchen.

As Peterson already has 45 tiles, so the more tiles she will need is:

$84-45 = 39\ tiles$

Hence,

Peterson will need 39 more tiles to completely cover the kitchen floor
