Find the slope and y-intercept of the line 6x−7y=2
Allisa [31]
To easily find the slope and y intercept of the line, put it in slope intercept form by rearranging the variables around.

6x-7y = 2
6x - 7y + 7y = 2 + 7y
6x = 7y + 2
6x - 2 = 7y + 2 - 2
7y = 6x - 2
7y/7 = 6x/7 - 2/7
Y = 6/7(X) - 2/7

Y = 6/7x - 2/7
Slope = m = 6/7
Y intercept = b = -2/7
(0, -2/7).

Raj's company ships T-shirts in boxes shaped like cubes. The picture below shows the cube
Rzqust [24]

Answer: The surface area of each cube is 24 ft² (24 square feet)

Step-by-step explanation: The boxes according to the question are shaped like cubes, which means the shape we have here has square faces on all sides. Also the boxes have been opened up into nets and this shows each box as having 6 faces.

The area of each face is derived as follows;

Area = L x W

Area = 2 x 2

Area = 4 ft²

Having calculated the surface area of each face, a box or cube with 6 faces will have its surface area as;

Area of box = Face area x 6

Area of box = 4 x 6

Area of box = 24 ft²

Therefore in designing labels for all of the boxes, Raj would need 24 square feet of label for each box.
