A:-2 B:-2/3 C: 2 D: 2/3 (The title is 2, is it wrong? )
(The answer is obvious, it is C: 2)
Oblique section of linear equation
The expression of oblique section is: y =mx+b, m is the coefficient or slope of straight line, and b is the intercept or intersection of straight line and Y axis.
The solution to the problem is to rewrite the equation 6X-2Y = -4 given to you into this format.
Now, start to change to y = mx+b format.
Step 1: 6X-2y = -4 X Project shift:
Step 2: Convert the coefficient of -2y =-4-6xy into 1 (that is, divide both sides by -2 at the same time).
Step 3: y = (-4-6x) ÷(-2) Now complete the division.
Step 4: y = 2+3x collate and convert into y = mx+b format.
Step 5: y = 3x+2
Next, try the following additional number learning exercises:
A. true/false: 6(Y+5) = 6Y+5, which is an example of the distribution rate.
True or false: 7(P+Q) = 84 is equivalent to 7P+Q = 84.
C. Right and wrong: an example of equation transformation of 5P-9Q = 9Q-5P.
D. solution: 7(X-2) = 8(X+3), and find the value of x.
