Does the tangent to y = x + 4 is the derivative of equation and = 1?

Question

I know some rule that the tangent of line is -y factor/x fctor = -1

Wh is right ?

Answer 1

deriv of equation is one

to use your formula for -x factor/ y fctr means it must be instandard form

-x + y = 4

and the correct way is - coefficient of x / coefficient of y

ANSWER: POSITIVE ONE

Answer 2

The tangent to y = x + 4 is = to 1 and that is the derivative. You can verify this simply by looking at the graph of this equation. Anywhere you look on the graph, the tangent line to the graph is 1, namely because the tangent line is the slope of y = x + 4.

Answer 3

The tangent to the line y = x + 4 is y = x + 4 for all x because y = x + 4 is a straight line, and not a curve. Its SLOPE (dy/dx) is 1 for all x.

Answer 4

I'm not quite sure what your asking, but derivite of the equation would be the slope of the tangent to the curve, and it is equal to one in this case.

y = x + 4
dy/dx = 1

A line tangent to a curve would have to be at a specific point, but because in this case it's a linear function, the tangent would be the same at all points.

Answer 5

son the equation is of a st line!!!! tangent is 1 like da!!!!!

Answer 6

yes it does

y'=tan (angle) =slope=1

angle=45 degrees
