Use the Slope Intercept form y = mx + b to find the slope m and y-intercept b.
Slope : 4
Y-intercept : (0,20)
Hope this helps !
Have a great day :)
Answer: two over three
Step-by-step explanation:

line intercepts y at (0,-2)
Therefore, 
Substitute x = 3 in y =ax-2

To find the x-intercept, y = 0

The slope is 2/3
y-intercept is -2
So two over three
Answer:
The surface area of the box as a function of the length of a side of the base is
.
Step-by-step explanation:
Let
be the length side of the square base and
be the height of the box.
According with the diagram the volume of a rectangular box with a square base is given by

and we know that its value is 9
.
The surface area is given by
S = (Area of Base) + 4(Area of a Vertical Side)

From the volume formula we can solve for 

and substitute into the surface area formula
