The equation given is:
15x - 3y = 21
Slope intercept form is:
y = mx + b
15x - 3y = 21
-15x -15x
-------------------
-3y = -15x + 21
/-3 /-3 /-3
---------------------
y = 5x -7
The answer is: y = 5x - 7

Answer:
142.24cm
Step-by-step explanation:
If 100 inches = 254cm then if you do 254/100 you will get how many cm are in an inch. 254/100 = 2.54
This means there are 2.54 cm in an inch. Multiply 2.54cm by 56 inches and you get how many cm are in 56 inches which is 142.24cm. This means Elena is 142.24 cm tall.
No question is asked so I'm not sure what you are looking for but below I calculated the point where the two equations intersect:
y - x = 4 → y = x + 4
y = - x² + 6x
x + 4 = - x² + 6x
x² - 5x + 4 = 0
(x - 4)(x - 1) = 0
x = 4, x = 1
when x = 4, then y = x + 4 = 4 + 4 = 8 → (4,8)
when x = 1, then y = x + 4 = 1 + 4 = 5 → (1,5)
The line and parabola intersect at two points: (4,8) and (1,5)
