if the x equals -1.2 and the y is -4, 4 what is the slope
4
yes.
y=-(8/7)x+4 Therefore, the slope= -(8/7)
The slope of f(x) = 3-4x is -4.

slope = coefficient of x = -4
The slope of f(x) = 3-4x is -4.
Slope of a line perpendicular to x-y=16
To get the tangent, you first need to find it's slope: y = x2 ∴ dy/dx = 2x So the slope with respect to x is equal to 2x. When x = 2 then, the slope is 4. Now you need the y-coordinate that occurs when x equals 2. We know that y = x2, so when x equals 2, y equals 4. You now have a point on the tangent, as well as it's slope, allowing you to define the line: Recall the definition of a line: Δy = sΔx or: y - y1 = s(x - x1) ∴ y - 4 = 4(x - 2) ∴ y = 4 + 4x - 8 ∴ y = 4x - 4 And that is your tangent.
The line x = -4 is vertical, so a line that is perpendicular to it is horizontal, so its slope is 0.
-4
the slope is infinite because you have a vertical line. To find a parallel line, the formula would be "x= any number" because that would also give you a vertical line.
