The equation y - 4x - 1 can be rewritten in standard form as -4x + y = 1. In standard form, the equation is written as Ax + By = C, where A, B, and C are integers, and A is typically positive. This form is commonly used in mathematics and allows for easier comparison and manipulation of equations.

Presumably this is a simultaneous equation in the form of: -4x+3y = 27 -2x+y = -1 Multiply all terms of the bottom equation by 2: -4x+3y = 27 -4x+2y = -2 Subtract the bottom equation from the top equation remembering that a - - is equal to a + Meaning that -4x - -4x = 0 and 27 - -2 = 29: So y will = 29 Substitute the value of y into the original equations to find the value of x Therefore: x = 15 and y = 29
8x2 + 2x - 1 = 8x2 + 4x - 2x - 1 = 4x(2x + 1) - 1(2x + 1) = (4x - 1)(2x + 1)
Without any equality signs the expressions given can't be considered to be equations
If the equation is x+4 the slope is 1. If the equation is 4x than the slope is 4.
