It is known that the triangle area between the line y = 2x and the coordinate axis is 8 after the line y = 2x is translated up or down

It is known that the triangle area between the line y = 2x and the coordinate axis is 8 after the line y = 2x is translated up or down

Let the line y = 2x, and the line y + M = 2x after up or down translation
Because when x = 0, y = - M
When y = 0, x = m / 2
The triangle area of besieged city with coordinate axis s = m quadratic / 4 = 8
M = positive and negative quadruple root sign 2
Just insert it
Can you give me a few examples?
Such as X chromosome, Y chromosome
What is the division rule of rational numbers?
Rule 1: dividing by a number that is not equal to 0 is equal to multiplying by the reciprocal of the number. (Note: 0 has no reciprocal) formula: a △ B = a × 1 / b
Rule 2: two numbers are divided, the same sign is positive, the different sign is negative, and the absolute value is divided. (0 divided by any non-zero number, get 0) formula: a △ B = a × 1 / b (B ≠ 0)
The line y = 2x, so that the area of the triangle between the translated line and the coordinate axis is 1, the analytical formula after translation is obtained
After translation, the analytic formula is y = 2x + B
Because the area of the triangle between the translated line and the coordinate axis is 1
Then 1 / 2 * b * B / 2 = 1 and B = ± 2
So the analytical expression after translation is y = 2x + 2 or y = 2x-2
After translation, area = 0.5 * x * 2x = 1, | x | = 1, so x = plus or minus 1
So y = 2x + 2 or y = 2x-2
The addition and subtraction of more than two fractions with different denominators can only be calculated from left to right, right?
Yes, from left to right is a calculation order, which will never change
The division rule of rational numbers is represented by letters
a÷b=a×1/b=c（b≠0）
A / b = C (B is not equal to 0)
Given that the inclination angle of line L is equal to 3x + 4y-7 = 0, and the area of triangle enclosed by two coordinate axes is equal to 24, the equation of line L is obtained
The slope of the line 3x + 4y-7 = 0 is - 34, so the slope of the line L is - 34. Let the equation of the line l be y = - 34x + B, let y = 0, then x = 43b, let x = 0, then y = B. since the area of the line and the two axes is 24, then s = 12|b|·|43b| = 24, then B = ± 6, so the equation of the line L is y = - 34x ± 6
In calculating the addition and subtraction of different denominators, what is the purpose of general division?
The purpose of general score is to convert different denominators into the same score, and then add and subtract the scores in the score
What are the similarities between the division rule of fractions and the division rule of rational numbers
All division, division type. Rational number is a little simple, fraction is a little difficult
The equation of the line L which is parallel to the line 3x + 4Y + 12 = 0 and the area of the triangle formed with the coordinate axis is 24 is______ .
Analysis: let the equation of line l be 3x + 4Y = a (a ≠ 0), then the intersection points of line L and two coordinate axes are (A3, 0), (0, A4), 〈 12 × | A3 | · | A4 | = 24, the solution is a = ± 24, and the equation of line L is 3x + 4Y = ± 24. So the answer is: 3x + 4Y + 24 = 0 or 3x + 4y-24 = 0
