You have given just one of the equations, and I guess you are looking for a formula for solving all linear equations.
I"d suggest looking at Cramer's rule for such a formula.

D = sqrt (x2 - x1)^2 + (y2 - y1)^2
(10,-8)...x1 = 10 and y1 = -8
(4,0)...x2 = 4 and y2 = 0
now sub and solve
d = sqrt (4 - 10)^2 + (0 -(-8)^2
d = sqrt (-6^2) + (8^2)
d = sqrt (36 + 64)
d = sqrt 100
d = 10 <==
Answer:
Step-by-step explanation:
For the first question the answer is 50(0.2 + 1)^2 = 72
For the second question it is y = 32
Step-by-step explanation:
In case you need to see how i got it...it's below
For number 1, y is proportional to (x + 1)^2
The equation would be y(x +1)^2 = k(the constant). Then I substituted numbers you gave me in the equation which was : 50(0.2 + 1)^2 = k(72)
For number 2 I used this equation: y (x + 1)^2 = 72. I substituted x for 0.5. The equation will be: y(0.5 + 1)^2 = 72. Then I got 32 for y.
Hope this helps:) i am the best lil kissman
Product means multiplication. So the equation would be xy ≤ 4.
