Find the slope for the equation 4x - y = 8.

-1/4
-4
4
1/4

The correct answer is: 1/4

To find the slope of a linear equation, we need to rearrange the equation into the slope-intercept form y=mx+b. In this equation, x is the independent variable, so we need to isolate y by subtracting 4x on both sides. This will leave us with -y=-4x+8. To get y alone, we need to divide both sides by -1, giving us y=4x-8. The slope of a linear equation is represented by the coefficient of x, which is 4 in this case. Therefore, the slope is 4, and the correct answer is D. As for the other options, A is incorrect because it reverses the sign of both the coefficient of x and y, making it -4x+y=8. B is incorrect because it only has a coefficient of -1, while an equation in slope-inter
