Algebra, equations and inequalities
Which of the following equations represents a line that passes through the points (4,7) and (2,-1)?
Select the answer:Select the answer
1 correct answer
A.
x + 2y = 1
B.
-2x + y = 5
C.
2x + 3y = 10
D.
3x + 4y = 16
To find the equation of a line passing through two points, we need to find the slope and y-intercept. The slope is (change in y/change in x) = (-1-7)/(2-4) = -4. Then using point-slope form, we get y - 7 = -4(x - 4) which simplifies to y = -4x + 19. Rearranging this equation, we get -2x + y = 5. Therefore, the correct answer is B.
Right Answer: B

C.
12x^3 + 6x^2 - 4x
D.
12x^3 + 6x^2 - 8x
The derivative of y with respect to x is dy/dx. Using the power rule, the derivative of 3x^4 is 12x^3, the derivative of 2x^3 is 6x^2, the derivative of -4x^2 is -8x, the derivative of 7x is 7, and the derivative of -2 is 0. Therefore, the derivative of y is dy/dx = 12x^3 + 6x^2 - 8x + 7.

To find the determinant of a 2x2 matrix, we subtract the product of the top-left and bottom-right entries from the product of the top-right and bottom-left entries. In this case, the determinant is (3*-1)-(4*2)=-7. However, the question asks for the absolute value of the determinant, so the answer is 7.
