Since there are no "following" points, none of them.
y = 2x-5 4x-y = 7 => y = 4x-7 2x-5 = 4x-7 2x-4x = 5-7 -2x = -2 x = 1 Therefore by substituting: x = 1 and y = -3
4x + 3y = 8x + y so 3y - y = 8x - 4x ie 2y = 4x so y = 2x
4x-y+7=0
y=xsquared-4x+2
No.
4x + y = 10 is a perfectly valid functional form. The standard form is 4x + y - 10 = 0
y equals 4x+1 is a parallel line to y equals 4x.
If the question is, Is y = x4 an exponential function ? then the answer is no.An exponential function is one where the variable appears as an exponent.So, y = 4x is an exponential function.
f(x) = 2x2 + 4x - 7
4x = y : or it can be written in the reverse order, y = 4x.
-4x=2y-16 +16 +16 (-4x+16)=(2y) /2 /2 y=-2x+8

The inverse of an equation is rewriting it as a function of the other variable. Simply solve the equation for x instead of y. y=9x can be written as x= (1/9)y --> fy=y/9◄ y=4x+6 (or 4x+6=y) -> 4x=y-6 -> x=(y-6)/4 --> gy=(y-6)/4■

Solve for what? Do you want to rearrange the equation for y to be a function of x? y = 70 - 4x Do you want to rearrange it as a function of y? x = (70 - y) / 4 You'll need to be more specific in exactly what you want done.
