How do i put this in slope-intercept form. passes through 2,-2 and 4,-1​
enot [183]

Answer:

\large\boxed{y=\dfrac{1}{2}x-3}

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have two points (2, -2) and (4, -1).

Substitute:

m=\dfrac{-1-(-2)}{4-2}=\dfrac{-1+2}{2}=\dfrac{1}{2}

Put the value of a slope and the coordinates of the point (2, -2) to the equation of a line:

-2=\dfrac{1}{2}(2)+b

-2=1+b              <em>subtract 1 from both sides</em>

-3=b\to b=-3

Finally:

y=\dfrac{1}{2}x-3

The surface area of the cube is 54 square feet. What is the length, in feet, of one edge of the cube?​
Brut [27]

Answer:

3 ft

Step-by-step explanation:

A cube is made of 6 equal faces each of which is a square with the same side length. The surface area of the cube is the surface area of one side multiplied by 6. We know the surface area is 54 so divide this by 6.

54/6 = 9 ft^2

Since the surface must be a square, take the square root of 9 which is 3 ft. The length of one edge of the cube is 3 ft.
