Answer:
y=3x-4
Step-by-step explanation:
Slope intercept form is : 
y=mx+b 
where m is the slope, and b is the y intercept. 
We are given the slope, it is 3. we are also given the y intercept, it is (0,-4). For this form, the 0 in (0,-4) is ignored, and we consider the y intercept to be -4. 
So, m is 3, and b is -4. Substitute the values into the equation 
y=3x+ -4 
y=3x-4 
So, the equation in slope intercept form is 
y=3x-4

Answer: 18 1/6 feet
Step-by-step explanation:
From the question, we are informed that the rectangular sand box has a length of 5 1/3 feet and a width of 3 3/4 feet. 
The perimeter would be calculated as:
= 2(length + width)
= 2( 5 1/3 + 3 3/4)
= 2( 5 4/12 + 3 9/12)
= 2( 8 13/12)
= 2 (9 1/12)
= 2 × 9 1/12
= 2 × 109/12
= 218/12
= 18 2/12
= 18 1/6 feet
